The two torches are well built and nice and bright and the handlebar mounts are high quality and work well. The rear light itself is OK but the fixing to the bike is a little wobbly. The rear light is best viewed as an added bonus.
This product reduced the appearance of the marks a little, but by no means was it a flawless repair. What I found worked really well instead was simply some Kiwi Instant Shine shoe polish - I mixed brown and black until the colour matched and dabbed it on. This repair is almost invisible and has remained colourfast for a couple of months now.
