No product is really deserving of a perfect rating but I had to give this product 5 stars because it has genuinely raised my standards of what a portable speaker should be... durable build, high quality sound, and a surprisingly deep bass for such a small package. It's comfortable traveling with me even if I slip it in the back pocket of some form fitting jeans and its sound is room filling. Longer battery life is the only improvement I could think of because I want to use this more than the battery will let me half the time and thats not a complaint i just use it entirely too much. Quality product no complaints here at all.
I purchased for my wife because the battery of the mini SoundLink that we bought almost 20 years ago is not lasting much, still exceptional sound.. We use it in the backyard. Excellent sound as all my previous Bose speakers I still have. More loud, clear and detailed sound if I can use the word. Beautiful design and color.
As expected this little speaker sounds like there's a live concert going on in my apartment and the only way it could sound any better is if there was an actual band playing !!!!
I have the first edition and now the flex 2, the ONLY reason I don’t give it a 5 star is the battery life is not what it should be for the money. I have a JBL that will run 2-3 hours longer and it was half the price. With that said, the JBL is far behind in build quality and overall sound. The sound is amazing and they are tough! I highly recommend them (just keep a charger near by for long use) or keep the volume down and it will definitely last longer.
