Buyer beware - try to borrow or rent a decent model. It may work if you are checking gross roundness; but not accurate work. Really a case of you-get-what-you pay-for, the dial indicator broke the first time I used it. I have used dial indicators in the past and this unit had a "gritty" movement.
I can't really think of any negative thing to say. The magnetic stand was quite powerful and the adjustment screws seemed appropriate quality for such a measurement device. I was a bit worried by some of the reviews that spoke of the parts being fragile and of lower quality, but I'm quite pleased by this set. Perhaps I'm not a machinist by profession, but I thought this set was great quality.
I found myself untightening and tightening it several times to get it at just the right location to measure the runout.I didn't want anything expensive and something that worked decently. Also the attachments take a bit of getting used to. This is the tool for you if that what you want. I've used it a few times to measure the runout of the brake rotors on my car. It works fine but the magentic base doesn't always attach itself well on curved suspension parts.
As was mentioned in another review, it would be nice if it included 1/64th graduations, which are much more useful than decimal values. That makes for some frustrating cuts.
Just not as precise as I'd like it to be. Oh well, its still a good value.
I bought this set because of the value, and it is one. I guess for the cost, Its a good value, but even the slightest touch to the adjustment arm after zeroing out the dial indicator leads to a several thousandths change in the indicator reading.
Definitely worth the price you pay, though. The caliper is surprisingly accurate for one in a combo set costing $30.
The magnetic base and dial caliper are another story.
However, the dial indicator is really pretty crappy, but servicable in most cases. What can I say. On the other hand, if you need basic calipers and a dial indicator may be useful on occasion (or you just want to play around), go for it. The main problem is it just not returning to full extention after being depressed and otherwise being "sticky".Anyway, if your primary want is a dial indicator, I would humbly suggest not getting this. cheap in both price and quality. Not a bad value, but not great.The calipers are pretty nice, and have gotten a lot of use.
