Took a punt for when I'm working in a garage etc. Arrived yesterday, fired it up, immediately got a row from my wife as the vibrations on the shelf knocked ornaments off. It's really incredibly loud and clear for it's tiny size! And at that price, I don't care if I lose or break it - which is nice

So yes - totally recommended, just need to work out if I can run more than one at a time ...
