Im in the process of select a dropper from Ali
Here is what I can see :
Racework
I just found this on AliExpress: | RACEWORK Wireless Electronic Dropper Seatpost 27.2/30.9/31.6mm Millisecond Response Mountain Road Bike Seat Post MTB Seat Tube

Meroca
I just found this on AliExpress: | MEROCA Bicycle Wireless Dropper Seat Post 27.2/30.9/31.6mm Electronic Control Millisecond Response MTB Road Bike Seatpost Parts
https://a.aliexpress.com/_EI5b5KQ
GTMRK
I just found this on AliExpress: | Wireless Dropper Seatpost Remote Control, Electric Height Adjustment Seat Post for MTB Enduro Bicycle,Quick Release Seatpost
https://a.aliexpress.com/_EvYTLGE
Riro
I just found this on AliExpress: | RIRO Electronic Dropper Seatpost Wireless Bluetooth Remote 27.2-31.6mm Adjustable Height for MTB Mountain Bike Cycling Parts
https://a.aliexpress.com/_EIBYSUW
Any clue? They look all the same, riro seems lighter for the same size and stroke, meroca seems a rebranding of gmrk, racework the less expensive, anyone tried one of these?
Thanks

I would recommend GTMRK https://it.aliexpress.com/item/1005010643108536.html (https://s.click.aliexpress.com/e/_c3yXrDyN), among all the droppers it is the one with the best reviews and also in terms of price it is not bad

Seekrun is not on your list?

but this is too heavy compared to others, racework ,gmrk or riro are below 650grams complete with trigger, referring to the 31.6 100/125 mm which is my sweet spot. btw the 27.2 is heavier because the main tube is made by steel instead of Alu.

The Riro is 646g + 52.3g in 31.6mm 125mm configuration. That's heavy.

31.6-100 :about 603g
the 100mm is more than i need

digging a bit into specs, the first 4 (meroca, riro, gmrtk and racework) look like they are all the same ELEVO or ELEVO-01 dropper, with 300mah battery and other specs exactly the same, the Seekrun has 400mah so this could make the small difference in weight of the S7.
-
i went for the Racework which is again available with a pretty good price, 31.6 x 125mm, i hope the declared weight (678gr) also includes the trigger, but i can't tell yet.

I picked this up, too, since it was cheap and had a 27.2/125mm post. I didn't weigh that one, but seems pretty good from using so far. One really annoying thing is that it unpairs from the button if you remove the battery. Not the end of the world since pairing is just pressing(holding?) both buttons together until you hear it actuate, but I like carrying my batteries in the car vs leaving them on if I'm transporting my bike. For the price, though, it seems pretty great. I paid $144 shipped from Aliexpress with no US tariff surprises. We'll see if it lasts, I'm assuming there probably isn't much for servicability.

Also mine arrived and it weights 678 grams as declared, 31,6 125mm.
Pairing was easy , utilization is also very easy and straightforward. Battery is hard to find here in Italy but I’m planning to test a 2032 or 2025
