Review on Bluetooth 5.0 Speaker by Celtic Blu - 16W 100ft Wireless Range with Surround Sound - Includes FM Radio, Built-in Power Bank, MicroSD Card Slot, Bike Cage & Remote (Black) by Thomas Taylor

I've been using the TallBoy multifunctional portable wireless speaker for about 1.5 weeks. This is a beautifully designed device that delivers excellent sound quality and is easy to use. I take it with me on long bike rides and it fits perfectly in the included mount! I have never had problems with instability when driving. There are a few design flaws that led me to give this product a 4/5 star rating. The buttons on the remote are too small for my big fingers and I have trouble adjusting the volume from the remote. Also, the protective flaps covering the DC IN terminal and the remote control terminal are difficult to open without using a special device. I think I spend more time opening them than enjoying stereo. I recently noticed that the volume automatically adjusts to a lower volume. It was at maximum volume for about 10 seconds, then settles down to a noticeably lower volume. I wasn't sure why this was happening, but then I noticed that the battery life was low, so it might be a balancing mechanism to extend battery life. I didn't like it but I understand the purpose. Also, I haven't downloaded the bass booster app yet as the product suggests, but I could. I agree with other reviews, the bass is a bit below average but not entirely unacceptable. TIP: Attach this stereo to your seat tube to really feel the bass :) Overall I like this unit. It suits my needs perfectly. I would recommend buying. Just note the design flaws I mentioned.
