Bad customer service sometimes, decent sometimes.
UPDATE: Disappointed with their support and customer service this time. I purchased a replacement remote after I lost mine, the new one arrived well, but its connection with the board is not solid. It randomly disconnects sometimes, and even experienced lags/glitches with braking/acceleration. If they knew remote re-pairing is finicky they should’ve made that clear from the start and I would’ve bought both the esc and remote together. When I reached out they just told me to ‘buy another one’ even though it has a 3 month warranty. Kind of unacceptable in my option. It’s a shame too because before this my experience has been decent with them. Original review: Good customer service from my experiences and decent shipping. As far as build quality goes, I have the Maxpro2, ive put it through the wringer for 4 years, it's held up pretty well. My board has always had an overheating problem where it slows down significantly after 3-4 km, but I cant complain too much because they sent me some replacement parts and I just never did it since I only need it for ~2 km/trip. overall I love mine.
