### ⭐⭐⭐⭐⭐ Loving this so far!
*by P***. on 25 February 2020*

Having looked at loads of these tumblers and been shocked at the prices charged, this one seems to be a bargain. Very well made and comes with everything needed to get started. Good sized strong drum and sturdy, professional feel base. Useful timer and speed controls. The drum on mine came with the additional metal end (not shown in picture) which does make it run ourt of true on the rollers as others have mentioned, but it pulls off easily and seems better for not having it on there.
