When this turned up in the post it was smaller than I expected and I began wondering if I'd bought the right product (even at this price). However, I was soon proved wrong. I took it outside one evening for a test and it's superb. The LED's are very bright indeed and the magnetic mount is much better than the suction cups I've seen on equivalent solutions. Build quality is very good, hammer is excellent and the blade on the seatbelt cutter looks pretty 'military'! I would recommend this for anyone to have in the boot of their car. Get yourself a warning triangle as well if you don't have one.
I also bought a dedicated hammer and seatbelt cutter to fit in the front of my car which I got off Amazon for under £5.00 (I reviewed it so you can find the link through my reviews). Get yourself one of those as well - you never want to be upside down in your car, smelling petrol and thinking "I wish I'd bought that item off Amazon". Sounds silly perhaps, but that was my take on it.
