I ordered this after having researched all the major child seats on the market. I needed a rack to attach a pannier and a seat that reclined and this was the best value product on the market.
Firstly the rack itself if off a very poor quality, it can be easily buckled by hand and has a 'plasticy' feel. A basic £15 rack from Halford is off a far better quality.
Secondly, there are lots of fiddly little bits and just one A5 side of very brief somewhat cryptic instructions and virtually no diagrams. I spent half a Saturday trying to work it out before finally realising that it was incompatible with my standard Marin Bear Valley bike.
I won't go into the technical details but they did include an alternative solution if, like in my case, the rack wouldn't attach to the seat end with their fittings. But, the alternative brackets weren't large enough to go around the frame, and they were so flimsy that I simply could not trust my childs safety on them.
I'm now either going to get the non rack mounted Raleigh on amazon for £20 or try halfords for a rack mounted reclining seat.
