I had jumped in on this also. Just got the two I ordered yesterday!
Yes, kinda on the cheap side, but better than what I have been building (boxed Vamo and LM2596 VV
mods).
I won't complain for two of them with shipping for under $21.
Clicky fire button, almost flush power and +/- buttons, love the locking feature and it's nice to have a power reading too (click power button 4 to 6 times for battery voltage)!
The best part, is that the Wife Loves it, 'cause she can lock the setting to her liking. She really hated that the Vamo she has gets changed when in her purse!! LOL
