## Questions & Answers

**Q: Is there any chance of the tumbler causing a fire if left on? For example if i went out would the tumbler be safe to leave on?**
A: tumbler has been left on for the day when i've gone to wrok, multiple times. Never caused me an issue. Motor shouldn't generate enough heat friction to start a fire, and electrics shouldn't cause an issue because the fuse would tirp out the electrics

**Q: How loud is it? Compare to something?**
A: The volume of noise will depend on many variable, but the decibel range will be 80-88. You can find many decibel charts online.  But for comparison this is in the range of a hair drier and truck level.

**Q: can it Polish sea glass**
A: Absolutely. We have tested various pieces of glass and it cone out looking really good.

**Q: What is the wattage**
A: Our Pro tumbler has a watts power output of 13 watts at max efficiency, the starter would be under this max.
