I received the xshaler last night and it's great for stripping barnacles and vaping to boot.
Finish is good
I put a freshly charge battery in at 3:30 pm and replaced it a 8:30 am the next morning with moderate use and about 7 hours of no use for sleeping. So not bad battery life.
Ergonomics, this is the first device with the button placement on the bottom (besides screwdriver) and it takes some getting used to. The 'action' on the switch is very nice.
With a LR 510, it performs just like a HV mod. It's thirst for juice is increased as well. With a standard 510 it delivers a hit just like any 3.7v device, I can't tell a difference between it and the performance of my eGo with a standard atty.
Fully assembled it stands a 1/2 inch taller than my eGo. So it has a very compact design.
Overall, very happy.
