Agreed, their bluetooth speaker reviews were lackluster. Ended up getting a UE Boom 2 after researching it myself and have been very happy. But for their other guides like travel gear, bluetooth headphones, monitors I've generally been happy with their picks. I usually pick the upgrade option when possible.
In my case I found a very detailed review on Amazon that compared it to a few competitors. I suspect UE makes good speakers overall though. For the UE Boom 2, it's sound quality was significantly better than the Anker speaker I tried and supposedly only 2nd to the Bose Soundlink Mini which is 2x the price and not waterproof.
