I chose this product, a bike store, because it was a police approved product. However the overall quality is let down by poor design and detailing, poor fixings, inadequate instructions and complexity of construction. In addition the Garden Street web page is inaccurate: it does not use gas struts but fairly primitive spring loaded ones. The ground anchor cable is also not alarmed. These descriptions apply to a more expensive and more secure product. The Trimetals website is overrun by 5* and 4* reviews with little negative criticism and a suggestion that construction is simple and takes around 3 to 4 hours. Check the reviews on Amazon and other sites as well as here - Trimetals are surely guilty of filtering out critical reviews? I can recommend the product but suggest care is needed and allow 12 hours (and assistance) to construct it effectively. I am a civil and structural engineer, experienced DIY enthusiast and at one time ran a DIY store so I think my criticisms are valid. Make sure you fix the store down with the anchors provided and against a wall if possible to avoid a massive theft risk if the back is accessible. Similarly, as reviewed elsewhere you MUST use the hasp and staples or the product is easy to gain access to. The problems: no tools are provided and the required tools are not listed. As many of the fixings are standardised and not therefore ideal in some locations, specific tools are needed to do the job right - particularly since many fixings have to be tightened in extremely inaccessible places, often requiring two people. Why on earth was a 3mm open ended spanner and 3mm slim box spanner not provided with this expensive piece of kit? Make sure you have them! The store can be purchased as non-secure and so rather than adapt their product, unbelievably Trimetals provide the components (and a drill bit!) to drill and fix your own hasps and staples. This is unacceptable in a product at this price. It requires great care to ensure everything lines up (and is inserted the right way round) to avoid ruining the store. Which raises the next issue, mentioned frequently elsewhere: the instructions are of low resolution, lack sufficient narrative and lack blow-up details at crucial points as well as missing critical sequencing steps. It appears that Trimetals may have never erected their own store! My copy was dated 2015...what a shame they do not read the negative feedback. I was provided with a useless masonry bit (buy a quality one - you will need an additional 16mm masonry bit anyway for the anchors) and two drill bits (presumably because their quality was such that one was insufficient to drill 12 small holes). Which brings me to the next issue: not only was I given two sets of instructions, one of which states at The End that they should not be used for Protect a Cycle but I got two sets of anchor bolts (of different types) and the instructions for anchoring did not match any of them or match the holes pre-cut in the base. If you think I am being hyper-critical, I recently also erected a secure shed from Biohort of Austria; this was superbly designed, detailed and manufactured and was complemented by all the tools required, brilliant instructions and helpful additions such as touch-up paint. What a shame their cycle store does not appear to be as secure.
