Great post for the budget minded. Highly recommend.
This dropper functions as described. Six month test has gone well as I ride mainly blue trails with the occasional black 2-3 times a week. Only thing to note is I have to slightly stand and relieve tension from post in order for it to drop easier, ie: slightly stand, engage thumb trigger, sit on post to drop. Great post for the budget minded. Highly recommend. Hope this helps. Happy shopping.

Manual lies.
The manual says that the pressure is adjustable. This is a complete lie, where it shows a valve stem in the manual there isnt one there, Its completely sealed. Considering returning it.

Decent budget dropper
I ordered the 36.1/125mm dropper. It's a direct fitment on my bike. However the installation instructions are difficult to follow. You are much better off finding a video on YouTube - specifically when it comes to getting the right guide cable length. If I followed the recommended instruction for measuring cable length I would have had too much slack inside my frame. The grip mounted control lever seems to be cheaply cast, there are better ones out there. Out of the box, the post is a bit sticky.. you have to cycle it up and down a few times before the seal works free. I also noticed a little bit of slop in the tube, even after everything is clamped down; the riser tube has a bit of play.

Technically it works.
Bought this for my wife's bike. It's too stiff to be much use for her. The lever is a hard push and flexes too much for it to work quicklly or reliably. Better options out there.
