Key safe
Good, sturdy key safe. Easy to fit. Number dials are a decent size and easy to change the code.

Good lock but change the label!
It's a nice sturdy keysafe, however it took me 4 X the amount of time and a broken thumb mail to get the large label off of the front cover than to actually fit the keysafe! In the end I had to go and get solvent (methylated spirits) as soap and water wouldn't shift it. Absolutely ludicrous!

Very tough
This is a robust, strong and well-made lock. I have bought two of these and they work a treat.

Solid, works well.
Feels very solid , well made. Got for occasional use and has been fine, can't foresee any issue with more regular use.Take reasonable care drilling 4 hols in the wall and it screws on very solidly. I have mine out of direct rain, but the exterior cover would do a good job at deflecting it. Easy to change combination. In terms of security : I think pretty hard to get off the wall, and then you'd still have to open it ; essentially it would be quicker and quieter to just break directly into the building. But I still only put a key in when I plan to use it ( I have another plan for unplanned scenarios ). One minor niggle : inside there are no hooks to hang things - so when the door open downwards to contents can fall out on the floor. Ok if it's not directly above a flower bed I guess. So minus 1 star for that; too harsh ?.

Easy to install and VERY TOUGH
This key safe ticks all the boxes: the combination lock is precise (i.e. no 'loose feel' to aid pickers) and has a useful weatherproof cover that, when closed, makes it look innocent like an electrical junction box. The best thing, though, is how tough it is - you'll be surprised by just how heavy it is when the package arrives. The small box weighs at least a kilo, very strong metal and the locking nubs are about 5mm in diameter each side. Basically, it's tough enough for nobody to bother with - it'd be less trouble kicking down most front doors. Another useful factor is the ease of installation - a metal plate acts as a "guide" to mark out the drill holes (all you need is a masonry drill and probably some plastic screw sockets to seat them properly). The metal plate then goes inside the safe, adding to its strength. Finally, it's a good size inside. Big enough for long keys, keyrings, and chunky electronic car ones, even unfolded. So no problem storing spare sets of everything in there. Overall, an excellent little product at a killer price (I paid £23.99.)

So happy with my purchase
Brilliant purchase. As I have been locked out of my house before a friend recommended this to me. Ordered and delivered the following day. It was very heavy. Easy to erect and set up with the change of combination that I could remember. The only negative thing I would say is the sticky label on the front of the casing was really difficult to remove for security reasons I did not want that on the front. I now have peace of mind that if I do get locked out again I can get back in😊.

Very sturdy and seems very secure
This key safe is not going to be used outdoors, it is ironically going to be used to keep my other safe keys safe. The key safe is weighty and when fixed to the wall it is immovable, it appears to be solid with the tumblers moving with no issues. Easy to recode - takes less than a minute. The safe is locked when you get it, when you remove the packaging the number is on the rear of the key safe - just cut the plastic ties an remove the solid plastic packaging and you will find it. Use the steel template that is inside the key safe to mark the holes on the wall - it took me less than 20 minutes to get it up and clear up after myself. All in all I would recommend this key safe. As for being waterproof - I have no idea and hopefully I wont find out if it is as its installed inside the property.

Solidly built - but appearances can be deceptive!
This is an impressive, heavy chunk of metal. It would take some serious work with a hammer and chisel to crack this safe open using brute force. That gave me great confidence to start planning where to install it to keep our house keys in. However, before I even started to unpack it I went online and found a YouTube video showing how to crack the code of this exact key safe in less than 30 seconds. It's a piece of cake and you can bet any house-breaker would have your keys out of this safe and be inside your front door before you could say "Bob's your uncle"! The solid appearance of this key safe inspires a high degree of confidence which the product doesn't deserve, so really it's worse than useless, hence 1* only. I returned this item (which was easy and painless to do - thanks Amazon!) Btw, ANY lock that uses combination wheels like this can be opened without the code very easily. If you doubt this, take a look online.

Pierwszy schowek przetrwał ponad 5lat(zmiana kodów się zacięła i kupiłem ponownie ten produkt) minusy są 2: - plastikowa osłonka odpada i nie chroni od warunków atmosferycznych. - po tylu latach mogli dodać haczyk do kluczy w środku

Compre este producto por las garantías que da la marca. Es pesado, yo lo monte en la ventana de mi casa y tengo acceso desde la ventana de las zonas comunes. Si pones un mando a distancia de alarmaes complicada de cerrar pues trae un espacio muy limitado, está pensado para llaves. En la foto del producto sale un mando a distancia, y no es viable o es muy complejo. Compre por la recomendación de Amazon un cable retráctil para las llaves, y más problemas. Al cerrar la puerta de la caja de llaves yo tengo que hacer mucha presion, cerrar y girar el pomo. No lo compraría para otro lugar y más aún para llave mando de alarma.

The first thing you notice when handling this, is the weight, It's heavy. I wanted something to keep my front gates keys in to enable people like my window cleaner access when I wasn't home. The only worry you have about these devices are; Are they physically strong enough to keep the key safe from forcible entry Are they big enough to hold a reasonable sized bunch of keys Are they easy to operate with the combination YES to all. It's heavy and it's strong. More than enough room for several keys and the combination lock is smooth and simple to operate. Fitting is easy too. It comes with an added, removable plate which gives extra strength to the actual fixing to the wall, but can also be used as a template for the fixing holes. Screws and wall plugs are included, but I preferred to use heavy duty fixing bolts to secure mine. A minor observation. I think the addition of a hook added to the back plate for hanging the keys might have been a good idea. I like this product so much, I replaced the one previously purchased to hold my spare house key, with one of these. Are they waterproof
