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! Review: 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 :-) ## Features - BOX APPLICATION: For indoor and outdoor use.

All good :-) ### ⭐⭐⭐⭐⭐ really nice case *by M***I on 12 April 2016* 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 :) ## Frequently Bought Together - Master Lock Mini Travel Safe Safe with Cable, White 5900EURD - Apple AirTag.
