I own a lot of highly rated BT speakers including the Bose SoundLink Gen 2, Harman Kardon GoPlay3, etc. Tried many models from bottom to top of their lines of the aforementioned, Marshalls, JBLs, Soundcores, W-King.

The Wonderboom 4 deserves is high user scores and accolades (NY Times Wirecutter #1 rated speaker). Great sound. Great battery. Reliable and stable with BT. It's small size and satisfying sonics is usually the one I grab first to go into the yard to watch sports on my iPad, etc.

For this sale price it's a no brainer.

It sounds nice inside. There's no lows but the mids and highs sounds nice.

Bought 2 of these thru Sam's club last year for $30 each. The BT is very solid as is the battery. Great for voice and podcasts. Lacks bass and crisp highs vs other units. Can get loud for its size.

How is the stereo/paired mode? Useful to get two of these?

I love this speaker, but this is pretty much the normal price now.
