Im solely a sound quality/tonality guy. These deadlift jacks solve all the problems, very easy to use and storable. I’ll keep if they charge and start working properly. I wanted to review it after first charge, but after two weeks use it still has about 20% battery in charging case. Yep this could fill a parking lot with sound. A little music quietly has allowed her to get to sleep faster and now she cant hear my sons lessons in the background. For $50 this more than suffices. It is not worth it. It’s really cool lol The only form of padding it has is a thin (rubber?) strip that easily gives way to the plastic underneath.
