DO NOT BUY! First of all the buzz is too loud to use in an acoustic or mic'd setting, it'll definitely end up on the track unless you actively work to hide it, paying $100 for a metronome that you have to hide in a real world situation is asinine. Perhaps the reason I'm writing this review is the poor experience I've had in dealing with Soundbrenner, Mere days after receiving the product it stopped buzzing, which is literally the feature of this metronome. A few days after contacting customer service it randomly started working again. A month or so later the Pulse stops working, apparently it was an issue with a faulty charger. After sending a video to prove it wasn't working they send out a new charger. A month or two after that it stops working again, this time the buzzing isn't working...again. Customer support asked me to send in yet another video to prove it doesn't work; this is now the third time in less than 6 months I've contacted customer service about this defective metronome. At this point I've reached out to customer service several times asking for a refund and they've ignored all my messages. Aside from the item being a largely unnecessary novelty product simply trying to reinvent the wheel (and failing) there's the abysmal customer service that lead me to unequivocally and in no uncertain terms strongly encourage anyone considering this or any of Soundbrenner's products to NOT buy and look elsewhere.
