This was purchased to bleed a Rockshox Reverb dropper post. The components in the box are good quality, and getting the whole thing set up was a matter of minutes. However, I recommend you have a friend help with the procedure, as although it is possible to bleed the system by yourself, the syringes are large and require a good amount of strength to transfer the fluid through the small lines. The kit includes a couple of spare o-rings for the bleed screws, which is a nice touch. I've used the kit about 4 times, and it hasn't shown any signs of leakage or damage.
