We're a party band. We play at least 50 events a year, each lasting about 4 hours. The drums were bought in 2023. The first problem was with the hi-hat, which started malfunctioning after only 4 gigs. There was an issue with a low-quality cable that was poorly soldered to the hi-hat's internal circuitry. We fixed that. In 2024, the kick trigger failed and we replaced it with a Roland KD-85BK 8" V-Kick Trigger, which is now working fine. Last week, the 'drum brain' started acting up and we're currently fixing it by restarting it. Considering the price of this instrument, we would expect it to work flawlessly for at least 4-5 years without needing any repairs or part replacements.
