Great build quality.
Simple to use.
I recommend picking up an AC adapter so you don't need to rely on the battery, though the battery itself is decent. Here's what I got:
[UL Listed] Chanzon 12V 5A 60W AC DC Power Supply Adapter ( Input 110V-220V, Output 12 Volt 5 Amp 60 Watt ) DC Converter LED Driver Lighting Transformer for 12 V 5 A Flexible LED Tape Strip Light
My problem: My unit arrived with a slight warping in the drive belt. Once I figured out how to contact the manufacture through Amazon (the only line of communication) they were quick to send me a replacement belt. I recommend removing the belt if you plan on storing the unit for anything more than a few days.
