Samson Expedition XP310w Portable Speaker with Microphone (Band G: 863-865 MHz)

I bought this as I have a number of other Samson wireless speakers and accessories , the most recent being a XP106w (100 watts power). I have enjoyed their quality and reliability to date.
As a quizmaster, I thought I needed a bit more power for larger venues with this 300 watt unit. Whilst the Bluetooth music might sound 3 times louder, the vocal power is certainly not 3 times louder that the the XP106. I had to use my own Samson XPD1 USB microphone as the supplied mic is very squelchy despite adjustments(possibly need more practice).
A few other things. The unit is very heavy, nearly requiring a second person to lift onto a speaker pole, and because of its weight gets very easily “jammed” on the pole, requiring assistance again to remove it.
Whilst the connectivity is good(which also attracted me to purchase the unit), having the control panel on the top of the unit makes it difficult to make adjustments mid-gig, especially when on a speaker pole.
I daisy-chain with my other Samson speakers when required, but overall am disappointed with its performance!
My view is if you get a chance to sound-check it before you buy, do so, (I didn’t!)as I’m not sure with hindsight I would have purchased the “last one “ left if I had to do it again.
