|only good for the front half|
Only it's not better. It sits so far forward that you can only tell if the front half of your bed is level. Better make sure when you buy your digital indicator to buy a pack of magnets too and just make the good one.
|the good one|
I didn't buy the magnets so I just had to hold it on. It still leveled my print bed real good. I'll stop by harbor freights to get the magnets, hopefully, before I need to level again.
