Review: Best purchase! Beyond happy with the capability of this tiny but mighty tool!! 10/10 worth it
Review: I think I got a dud the first unit I bought 18 months ago as it only lasted a couple of months before the main board or battery died. I tried a different unit for 6 months, but it lacked the same power. Not that this has real ‘grunt’, but it is still much better than the replacement I’d bought. This new unit has held up without issue for the last 6 months.
