The details
Small penguin, big noise
Four details that make the alarm easy to use – even in the dark and in a hurry.
The LED light
Lights up the keyhole, front door or path. Switch it on and off with the button on the belly.
The pin and strap
Pull out the pin – the alarm sounds instantly at 130 dB. Push it back in and it goes quiet.
The button
Sits on the belly and only switches on the light. A bump in your bag can never set off the alarm.
The keyring
A metal keyring for your keys, your bag's zip or your backpack strap.

Why the ORVO personal alarm
Peace of mind that's always with you
One tug is all it takes – the alarm does the rest.
130 dB
Heard when it matters
A piercing siren that cuts through traffic and wind, makes people turn round and scares off anyone who gets too close.
1 tug
On in a second
No fiddly button to find under stress. Pull the strap and it screams – and keeps going until you push the pin back.
LED
Light in the dark
The built-in light finds the keyhole in your front door and lights up the last few metres home.
Keyring
Always with you
Clips onto your keys, handbag or backpack. The cute penguin looks like a keyring – not an alarm.
Nothing to download, nothing to pair – ready to use straight away.
Dark eveningsSound familiar?
The last stretch home
Dark by four, empty streets and a walk from the bus stop. Keys in your hand, phone in your pocket – but there's no time to call anyone when something feels wrong.
Pepper spray is illegal to carry in the UK, and a whistle needs breath and calm.
Feeling safe should be right where your hand already is.
The light at the front doorORVO personal alarm
One tug – and everyone hears
The penguin hangs from your keys or bag. Pull the strap and the alarm screams at 130 dB, so people nearby react and anyone too close backs off.
And on the way home the LED light finds your keyhole.
- 130 dB alarm with one tug
- Built-in LED light
- Battery fitted – ready to use
Small enough for every day. Loud enough when it counts.

Personal alarm vs whistle
Both are meant to be heard. Only one works when you're scared and out of breath.

Everyday life
With you on every walk home
On the backpack, bum bag, tote bag or in the handbag – where customers carry their alarms.
I walk home from the Tube late several nights a week. Now the penguin's on my keys and my hand is on the strap for the last stretch.
Emma, London
I run after work when it's already dark. I keep the alarm on my bum bag and feel so much safer.

Mum walks on her own every evening. She understood straight away how it works – just pull the strap.

Questions & answers
Common questions about the personal alarm
Can’t find the answer? Email support@eoka.se and we’ll help you.
Hold the penguin and pull the orange strap. The pin comes out and the alarm sounds instantly at 130 dB. It works just as well with gloves on and in the dark.
Push the pin back into the hole and the alarm stops straight away. Until then it keeps screaming – even if you drop it.
Roughly as loud as an emergency siren up close. The sound is piercing and cuts through traffic, wind and crowds, so people nearby react.
Press the round button on the penguin's belly. Press again to switch it off. The button only controls the light – it never sets off the alarm.
No. The pin sits firmly and it takes a deliberate tug on the strap. Rubbing against keys or being squashed in a full bag isn't enough.
No. The battery is fitted when it arrives and there's no app. We recommend a quick test tug once a month so you know everything works.
Yes. There's only one thing to remember – pull the strap. Many buy it for school kids and teenagers who walk home alone, and for older parents who want to feel safe on their walks.
Yes. A personal alarm isn't a weapon and anyone can carry one anywhere. Pepper spray, on the other hand, is illegal to carry in the UK.
The keyring fits your keys, your bag's zip, backpack straps and bum bags. Hang it where your hand reaches it fast – not at the bottom of your bag.
Yes, it's one of the most common reasons people buy it. Many choose the 3-pack: one for themselves, one for their daughter and one for their mum.
Choose 3 alarms and you pay for 2 – the third is free. With 2 alarms you also get a pack price. The discount is applied automatically in your basket.
We ship within 48 hours and you'll get a tracking number by email. Shipping is free on orders over £34.99. You have 30-day returns from the day you receive your parcel – email support@eoka.se and we'll help you.

Sophie, Manchester01/11/2026
Always in my handbag
Clipped to the zip of my handbag so I can grab it instantly. Cute enough that nobody guesses it's an alarm.
Karen, Leeds30/10/2026
Bought for my daughter
My daughter is 13 and has started getting the bus to training on her own. She thinks it's adorable, and I'm calmer.
Hannah, Bristol27/10/2026
Properly loud
Tested it in the hallway and the whole family came running. The cat hid under the bed for an hour.
Lucy, Brighton25/10/2026
Looks great on my tote
Hangs on the tote bag I take everywhere. The orange strap is easy to spot when you need it.
Rachel, Sheffield23/10/2026
The light is worth its weight in gold
Our front door has no outside light. Now I find the keyhole straight away with the little lamp.
Jess, Nottingham20/10/2026
On my evening run
I run after work when it's already dark. I keep the alarm on my bum bag and feel so much safer.
Ellie, York16/10/2026
In my backpack for school
Clipped to the loop inside my backpack. Easy to get out and it just looks like a normal keyring.
Margaret, Norwich13/10/2026
For my mum, 78
Mum walks on her own every evening. She understood straight away how it works – just pull the strap.
Sarah, Cambridge11/10/2026
Three alarms for the family
Got the 3-pack: one for me, one for my sister and one for my daughter. Great price with the offer.
Fiona, Edinburgh09/10/2026
Works in the cold
On my keys in freezing weather with gloves on. Still easy to grab the strap.
Nicola, Newcastle06/10/2026
Calmer as a night nurse
I walk to the car at 11 pm after my shift. Now I've got the alarm in my hand all the way across the car park.
Laura, Reading04/10/2026
Sits next to my keys
Hangs on my keyring on the hall table, so I never forget it when I head out.
Jenny, Southampton02/10/2026
Cute and useful
Everyone asks where I got the sweet penguin. Then they're surprised when I tell them it's an alarm.
Lisa, Coventry29/09/2026
Easy to use
No app, no charging, no faff. One tug and it screams.
Helen, Bath25/09/2026
My daughter in the city
My daughter studies in London and often walks home late. Lovely to know she always has it to hand.
Joanne, Chester22/09/2026
Best present
Gave one to each of my friends for Christmas. They all loved it and have it on their keys now.
Amy, Cardiff20/09/2026
Finding the door in the dark
The light shines exactly where I need it at the lock. Luckily I've only ever tested the alarm.
Julie, Inverness18/09/2026
Dark dog walks
I take the dog out late in the evening through a wooded area. The alarm is clipped to the lead handle.
Pauline, Harrogate15/09/2026
Easy to understand
I'm 71 and not very techy. This needs nothing from you – pull it and it sounds.
Louise, Plymouth11/09/2026
Worth every penny
Peace of mind that doesn't cost much. Wish I'd bought one sooner.
Molly, Oxford08/09/2026
Doesn't look like an alarm
Nobody would guess the penguin can be that loud. That's exactly why I wanted it.
Kirsty, Glasgow06/09/2026
Two for the kids
Bought two for the twins starting secondary school. They don't even argue about who gets which.
Becky, Bournemouth04/09/2026
Safe at the festival
Had it on my bum bag all weekend. Felt reassuring in the crowds at night.
Alison, Aberdeen01/09/2026
Solid
Feels sturdy, not like a cheap plastic toy. The pin sits tight so it doesn't go off by itself.
James, Guildford28/08/2026
For my wife and daughter
Bought three. My wife has one on her keys, my daughter on her backpack and one lives in the car.
Brenda, Torquay25/08/2026
Heard all over the house
My hearing isn't the best, but I can hear this alarm from the other end of the house without a problem.
Chloe, Milton Keynes23/08/2026
No button to hunt for
The best part is the strap. When you're panicking you don't want to search for a tiny button.
Natalie, Canterbury21/08/2026
Just the right size
Fits in my hand and takes up no room in my pocket. Weighs next to nothing.
Katie, Lancaster18/08/2026
Commuting in the dark
I commute by train and cycle the last bit. The alarm is on my handlebars and the light helps at the bike rack.
Jessica, Surrey16/08/2026
The whole family has one
Got the 3-pack. Now everyone in the family, even Nan, has their own alarm.
Christine, Worcester14/08/2026
Recommended
Simple, loud and does what it says. Already told my colleagues about it.
Maisie, Belfast11/08/2026
Gives me peace of mind
I've been in some unpleasant situations before. This little thing means I dare go out in the evenings again.
Gillian, Kendal09/08/2026
Tip: hang it where you can see it
At first I had it at the bottom of my bag. Now it's on the strap, where my hand finds it straight away.
Holly, Durham07/08/2026
Perfect for uni
Mum gave it to me when I moved into halls. It's on my keys every day.
Barbara, Salisbury04/08/2026
Quick customer service
Emailed a question about the battery and got a reply the same day.
Natasha, Croydon31/07/2026
The right buy
Wanted something legal and simple since pepper spray isn't an option here. This was spot on.
Rebecca, Stockport28/07/2026
Tested for real
A man followed me from the station. I pulled the strap, he turned and walked off immediately. So glad I had it with me.
Emily, Carlisle26/07/2026
Cute and clever
Thought it was a gimmick, but the sound is genuinely loud and I use the light every day.
Lottie, Cheltenham24/07/2026
My daughters love them
Bought three – one each. They have them on their school bags and proudly show off their penguins.
Yvonne, Dorking19/07/2026
Safe on holiday
Took it on our trip to Barcelona. Nice to have in the evenings in unfamiliar back streets.
Alice, Whitby17/07/2026
Clean and simple
No app, no battery to charge. Just a little penguin that sounds like a fire engine.
Susan, Hereford14/07/2026
Good quality for the price
With the offer it was cheap to get alarms for the grandchildren too.
Matilda, St Albans12/07/2026
Buying more
Going to buy one for my sister. Best thing I've bought this year.
Claire, Leicester18/10/2026
Good, wish there were more colours
Does exactly what it should and it's loud. Would have liked a darker colour for myself, hence four stars.
Kate, Exeter27/09/2026
Good, the light could be brighter
The alarm is seriously loud. The light is fine for the keyhole but not for lighting up a whole path. Four stars.
Megan, Swansea30/08/2026
Waiting for the dark evenings
Only tested the alarm at home so far and everything works. Four stars until I've used it more.
Tilly, Ipswich21/07/2026
Good, but check how the pin goes in
Works well. Four stars only because I didn't realise the pin has to go all the way in for the alarm to stop – my fault.
Gemma, Derby13/09/2026
Great alarm, annoying delivery
The parcel ended up at the wrong pickup point and I had to go and collect it. The alarm itself is brilliant.
Wendy, Shrewsbury02/08/2026
Box was a bit battered
The outer box was damaged in transit but the alarm was perfect and works fine.
