United StatesGood but has issues
its pretty good when it will hold a charge. I can charge this all night and then roll one cone and come back the next night and battery will be dead even though unit was shut down after last use. It frustrating having to always keep it on a charger ready to use. Other than that, it does what it says it will do although the dryness does make a difference.
United StatesGreat Cones!!!!
This cone roller by Banana Bros is an excellent device I'm so glad I bought it. I’ve had it now for a little over a year & it holds a charge great, the cones produced are uniform & it’ll pay for itself within 6 months.

Bought for my wife as a b-day gift. She got it early and loves it. Works as advertised, still have not figured out how to pack the cone tight. Worth every penny. ðŸ˜
