Review on 🔊 LEHII Outdoor Waterproof Shower Bluetooth Speaker - Portable Wireless Speaker with IPX7, TF Card Support, FM Radio, Hook - Ideal for Outdoor Travel, Swimming Pool, Beach, Bike, Office - 8 Hours Play Time by Ron Houston

First thing I checked was the sound quality and I was really surprised at how clear it was as the initial 'voice' saying 'Bluetooth connected' sounded awful. Once connected to my iPhone, the sound quality was very good. I tested all the buttons and they work as expected. FM Radio - No display and no way to save the various presets I see. There is a scan function that switches between stations quickly and is difficult to stop at the desired station. Luckily, you can press and hold for 2 seconds to scan for any station. The sound quality was good for FM radio but I wouldn't use it for radio as it's a very basic function. I didn't use a TF card because I didn't know what it was, but after a while I got curious, it's just a micro SD card! Thanks for that as I thought it was obscure technology for that. TF Card = T-Flash = TransFlash = microSD = microSDWaterproof - I'm sure it's water resistant and not actually waterproof as I wouldn't trust putting this in a bucket of water but if you put it in the shower it will away from the direct current, you should be fine. My biggest concern with this device. If you are looking for a decent sound to connect to music via Bluetooth then I think you will be happy with this purchase!
