Customer Reviews

I was not impressed that the advertising stated this was rechargeable usbc. It came with no batteries or usb cable. Instructions said to use 4aaa batteries or 3.7v lithium ion battery. I used aaa batteries but in some modes the device tries to charge the batteries. Not good. Tried 4 aaa lithium batteries but too much voltage so it kept killing one battery. Pulled out the springs and plates and opened up the battery compartment with a die grinder and fitted a 3.7 lithium pack. Now it works fine and is a really great tool. Shame it didn’t come with one.
This tool is fantastic. Accurate, quick and is so easy to use. Thanks discount tools.
