LOL advice may be “off” but when the importer/person flogging the stuff publicly says they are not going to handle the returns anymore then starts to flog them off cheap I would want to know. Dropper posts have a habit of going wrong….
I got mine through SS and it failed, it was repaired by the other half of then and sent back fine. I would like to know who is going to be doing this if I sent it back before buying as it sounds like bridges have been burned.
However reading between the lines of your post…
Go for it what could possibly go wrong (it’s your money)
