Screen glitches like crazy

Darkening effect went out once during use right in the middle of welding. (No, that wasn't scary at all *sarcasm* ... and a little blinding). The screen does not work at all like it should. I find I have to hit the top part just above the screen most every time I use it. The screen will flicker before coming on. Sometimes it will release back to normal visibility. Sometimes. If it doesn't ... *whack!* to get it to stand down. The battery compartment has come apart along the top as the battery cover is a severe PITA to remove. (Removed battery to check it to make it wasn't dying and causing the problems). Save your money. Get something better
