There are three versions available. The safe we looked at in this review was Flexysafe Pro, introduced to the mobile security market this year. The company describes the product as lightweight. However, at 8kg, it isn’t exactly feather-like. The very bulk of the safe would intimidate thieves and anything placed inside would be well and truly hidden from the uninvited eye.

The standard internal measurements are 450mm (length), 135mm (width) and 367mm (height). The powder coat black-coloured safes can be custom made to a particular size and specification on request, which gives some flexibility. The Pro comes with a seven-lever lock mechanism but no bolts or screws.

The fixing method is by means of a metre and a half long, fabric covered hardened steel strap that measures about 4cm across. This impressive looking cable weighs over 3kg alone and looks like the sort of thing you would use to secure your motorbike.

The system is designed so that the device can be secured to an anchor point found in most cars: either behind the passenger seat or in the boot. Two keys are supplied: one for the cable lock and one for the safe casing. Anyone withoutthese keys would find it tricky to remove the safe from its anchorage point without being disturbed.

FOR A heavyweight solution for site offices and commercial vehicle fleets. AGAINST The mass and price of the device would not suit everyone. VERDICT A reliable, resistant security solution.

The unit comes with quite a nice feature: a charger unit cable access hole that means electrical items can be recharged while locked in the safe. Handy when you’re on the road. Relocation from the car to the office or home environments is a possibility but the sheer weight of the case does not make it particularly portable. The product is also quite expensive for most tastes.

Another version of this security case that retails at a lower price of £95 is the Flexysafe Utility, which offers commercial vehicle fleets a solution for protecting laptops and other expensive equipment out in the field. Similar in build and size, this safe bolts directly into commercial vehicles.

The Flexysafe Utility has a two-fold benefit: the safe helps protect against theft and accidental damage, and in order to recharge any equipment, security-lax engineers are forced to house the equipment inside the casing. Both would be suited to larger scale operations where insurance costs could be considerably reduced by investing in something like the Flexysafe security cases.
