A great solution for holidays at the beach
This is great. I bought one for myself and one for my mum to use on holiday so we can leave our bags locked to our loungers with our money and phones inside when we go swimming. It fits my iphone 6, keys and some notes / coins in it and is easy to use. It seems pretty high quality but i assume that if someone really wanted to steal it and had heavy wire cutters that they could. However i'm not sure getting into the actual safe is going to be easy. It has a 4 digit pin system so if someone went through all the options there were it would take them a long time to open it! A great deterent and a great size. Lots of uses but it is quite heavy for it's size so you need to factor that it. I wouldn't cart it around a city sightseeing trip unless it was maybe a really high pickpocket area and i wanted to lock it to a belt or something... However, i would probably opt for a waist bag belt! I would however use it in hotels for extra security, in restaurants, at the beach, clip it to the pram for out and about with the baby - i've had my purse stolen out of a bag attached to the pram before. It's a very well built item too. I recommend them to everyone!

Yes small,pretty tough and may a little heavy,but..
Yes,item is as good looking,pretty strong and maybe a little bit heavy. Very good for when you travel and haven't got anywhere safe to put you personal small belongings safe,when you fancy a sleep ,on the beach,out and about,travel in your car or in a hotel were there is no safe.it is a little bit small. You can get quite a bit of money,credit cards and your passport inside of if..(just). Well,I normally use the safety steel rope to also attach my small bag to it and the to somethings solid for 2 for 1 security. Well,it works for me.. All good :-)

really nice case
Excellent item. This is a solid item. Not a flimsy bit of plastic. I can fit my keys, wallet and iphone 6 into this case. I think iphone 6 plus will be a little to big. One thing I do like is that the cable release and the button to open the case are 2 different buttons. The plus side is that they are press release buttons, and not slide buttons. Which means someone can't apply tension to the button to figure out the combination. This item is to deter the snatch and grab thief. I would not recommend using this as a safe which you are going to leave unattended for several hours. edit: This item is not family borrowing proof, Item is so good just had to replace the one I bought over a year ago, because a certain person borrowed it, fell it love with it and doesnt want to give it back :)

Ideal when travelling.
Very sturdy and seems like its pretty secure box, in the photo we have two passports a pen & a large mobile phone and was able to shut it without any problem. Think it's good for your most valuable items when travelling. It is heavier than I thought.

Internal size disappointing
Was rather disappointed with this product. It looks good, well made, a bit heavy, but the inside was rather small. The picture is incorrect as after putting my iPhone 16 (not a plus or a pro) there’s not much room for much else. I have a bunch of keys, which after that I could get maybe a ring or necklace; to hold that and passport, not possible, so disappointed but couldn’t be bothered to send it back. Only good thing, I bought it when the price had dropped

Perfect for travel
Safe and secure - able to hold passports money and phones etc. we secured to pipework in bathroom and always felt confident leaving the room. Would recommend to anyone rather that using the dodgy hotel safes

Good item, glad we have it.
More of a deterrent then a full secure safe (with a bit of aggression and 5 minutes I reckon you could stamp it open) but we wanted it for inside the safe to protect from casual thief at the hotel, and for chaining inside our luggage when we needed to carry money / passports in 2nd world countries, for this it was a great thing to have and made us feel more relaxed. I bit heavy, but I guess that is par for the course.

Not a bad idea
Although it's not been on a trip yet, this seems sturdy. Everyone will be wondering how big it is-- I'll say this, I could fit my smartphone, passport and money in it. I can also fit my compact system camera (on its own) with the lens off. It's not light (I'd say about a Kg). My advice for this sort of thing is to not leave it on show anyway- if they want to take it they would find a way, but it will give you peace of mind- locked to something sturdy and hidden away. It's cheaper than a Pacsafe Travelsafe, the only alternative I could think of. I bought another after playing with the first.

Ten zamek może wyglądać solidnie, ale w moim przypadku zawiódł niemal natychmiast w warunkach, do których rzekomo jest przeznaczony. Po jednym dniu na plaży niewielka ilość piasku w mechanizmie sprawiła, że stał się całkowicie bezużyteczny. Jak na produkt mający chronić cenne przedmioty na zewnątrz, nie zapewnił żadnej niezawodności i zostawił mnie w trudnej sytuacji. Zdecydowanie polecam poszukać bardziej wytrzymałej alternatywy.

Suveränt att kunna välja kod och låsa in pass, kontanter och värdesaker på resa (och hemma) Passade min mobilplånbok perfekt så korten var säkra… mannens plånbok liiiite för bred tyvärr. Vajern var lagom lång.

海外旅行のため購入。 大きくて少々重いのは、金庫と思えば問題ないが、思ったより大して物が入らない。 大きめのモバイルバッテリー・ガラケー・パスポートでいっぱいいっぱい。 しかも、若干工夫しないとパスポートが入らない。 内側、ウレタンでカバーされているが、きっとすぐにボロボロになりそうな予感。 見た目は好き。 タイの空港のセキュリティチェックで引っかかり、中を見せたが、日本とネパールはスルーだった。
