No AA or AAA battery fits this item, the documentation is useless in telling you what battery it uses, however the advertised pictures on the actual manufacturers web page shows a battery included and the odd thing is that it sells for the same price as amazon on their own web page, BUT includes the battery. How on earth can this company expect you to use this product without a battery or even a mention of what battery to use!? There are other products which are alot more complete for less money which include a battery. Once i have managed to figure out what battery this uses, i will post more info on the products actual performance.

I didn’t like that it had no battery and I have not been able to use it . I am in the process of trying to find a battery for it. Useless without it!!! Would not buy again

I was skeptical at first between the price and claim to be within .0002 repeatable i was sure it was a bs but after extensive testing I've gotten it within .0003 repeatable. I've only tested it on my machine a 30 year old Horizontal and its a bit touchie but I believe that the .0002 is posable. I still prefer to use my indicator to pick up but this thing is pretty cool. 5/5

Unfortunately, the runout on this item was around 0.008", which is just too high for what I want to use it for. I did like the nice loud beep. I didn't find it to be painfully so as others have reported.That combined with the (for my shop) odd 20mm size of this item meant that I'll be returning it. It's too bad, because I would prefer an audible alert so I can keep my eyes on the DRO or the dials while touching off. The visual-only ones mean I have to be looking at the tool. If this thing had runout in the 0.001" range, I'd probably have kept it, even though the large, metric size makes it less convenient than a smaller one sized for imperial tooling would.Maybe I'll make my own - what I want doesn't seem to exist.

Seems to be really nice quality..nice fit and finish...the beep is nice and loud...led brightness is perfect......has a bit of weight to it...seems a little long..but its fine....i used a 3/4 collet instead of 20mm...worked fine and snugged up nice.......repeatability seems pretty spot on...will edit this review after i usee it more...

Haven't actually used it yet but I checked the run out on the ball, .0015 isn't perfect, but a lot better than I expected.

Surprising quality, comes in a nice little wood case. Very accurate, well under 0.001". Just like the description says, the object being sensed must be metal. Doesn't work on plastic, etc. However, you could use this on plastic if you used a grounded shim of a known thickness, then just subtract that thickness from the dro and you know the edge. Includes the battery as well.

After checking reviews on this and other similar items I decided to take the risk and I’M GLAD I DIID ! I found the item to have a great surface finish and overall looked great out of box ( especially for price ). For those that claim this doesn’t work it’s because they don’t have it mounted in a electrically grounded machine. I repair CNC machines and once mounted in spindle the unit has a bright light and loud beeps that would come on and off with .0001in. accuracy. I haven’t had it long enough to review battery life but glad I purchased this item !
