Too bad to hear that. Hope they fix it (again) like they did just a weeks ago
If you want to look elsewhere I must note that these post are not identical to the originals.
I found that their pots have way less precision that the originals. You can only use 42 steps/positions instead of 255 (1/6th), but hey, I use this with my feet, they are not so precise either
This leads to a small spiking because it can't use the real position. For example, if you want to use the position 127, it would change between 125 and 131. The jumping is always those 6 deegres due to the way they are build (300 working deegres instead of 70º).
I don't regret the purchase, but I hoped they were identical.
