Review on MIDOLA Bluetooth Speaker: 40W HiFi Sound, IPX7 Waterproof, 20-Hour Playtime & Stereo Pairing for Phone, Pad, Tablet & TV – Wireless 5.0 Dual-Drive Tri-Bass Portable Speaker by Isaac Logan

Selling for under $20 this is exceptional value. At full price, it's still a pretty decent price. Sounds comparable to my Echo Snow 8, which is good. Midola t8 is also very durable. Smaller than you would expect (maybe 9 inches wide and 4 inches high, more or less). I assumed it would be more with (ahem). requirement of 40 watts. It would be nice to put under the monitor. I doubt it's 40 watts. slightly louder than my 20 watt echo. But there's storage, USB-c charging, etc. If you only have $25, it's easy to recommend. It has IP67, which means it can survive being submerged in water. Many competitors have the IPX5, which is only splash and hose tested. It's premature to comment on battery life, but there are no discernible issues. But I rarely use advanced sessions. It's much quieter and smaller than my 30 watt speaker and the sim car echo show volume is 8. That's 2 speakers x 10 watts. For 20W. Corporations can manipulate power, so be skeptical. Edit: I ordered a second one and can't seem to pair it, maybe it's user error. 4 stars seem correct, but 40 watts of volume cannot be. I got it for $25 with another 25 percent off.
