Not got one myself but have fit two of these recently on bikes I look after for friends.
Yes, don’t expect Thomson/RS quality or infinitely adjustable seathead as its serrated so you have a fixed few degrees of movement each time.
Do expect a seatpost that works really well and with a bit of faffing its almost as good as the big hitters in the market. Also the black stanction looks really good.
Few things to watch out for:
100mm travel only
Lever throw not quite long enough(resulting in preloading cable so its finicky to get spot on – even with inline barrel adjuster)
When it gets a bit crappy(err this is the UK) the lack of lever throw means it doesn’t always actuate the best, more tension on cable results in always activated so very bouncy seat post.
Best remedy we have found so far is a length of spring to go between the actuator lever and the cable stop. 3 weeks in and its working faultless.
For £100 its a no brainer as its very close to the boutique posts for very little money. Possibly requiring a bit more fettling along the way to keep lever action good
