The best one I have possessed! Furthermore, being a wino, I have had a few. Quick and genuinely tranquil. The thwart remover in the base is likewise the best of any that I have claimed over numerous years, including some enormous name brands. Claims up to 180 containers on a solitary charge. I have recently passed fifty containers without reviving. Will catch up with the aggregate when it should be charged. The Amazon page expresses a multi year guarantee however the proprietors manual expresses a multi year guarantee. I reached the organization and they said all units sold in 2017 and past convey a multi year guarantee! A large portion of my different openers had battery diminishment or disappointment inside a year. Li batteries, for example, the one in this opener by and large last numerous years. It opened 90 bottles before requiring a revive. Stunning!
