1.0 out of 5 starsNO BOOST! Limits the volume of music played, long recharge, and doesn’t hold charge.
September 8, 2019
I purchased two of these units, one for my BMW Z4 and another for my Mercedez Benz E350 4matic and iPhone XS MAX. Although this product has a higher price than some of its competitors, I believed, based on the description that it would be a better product. I was wrong. This product claims to have a BOOST feature; however, it does not work. The device takes a long time to recharge and does not hold its charge for more than one day. Most importantly, the device limits the volume of music played. Both of my vehicles have terrific sound systems with many speakers. When I am driving in my convertible, I like to listen to music loudly. FORGET IT! It limits or reduces the amount of sound output. Cheaper versions of this product (e.g., Walmart $7.99) performs better than this product. Nulaxy used to have a similar device, priced significantly less, but it is not available on Amazon anymore. Do yourself a favor and do not purchase this product - coming from a technical expert with over 25+ years' in the technology industry.
