4929 Valve Spring Height Micrometer Measurer, Black Aluminium, 1.600"-2.200" Height Range Precise Readings, Covers Most V8s

Easy to use

It is not accurate due to poor quality and manufacturing. Do not recommend at all!

Please refer to the photos: This tool has a .020" error in it's calibration. When it indicates 1.600" it actually measures 1.580" with a digital caliper. In each photo you can see that the indicated value is off by .020" when actually measured. In the case of photo #6 the tool is indicating a value of 1.850", but the actual measured value is 1.830". I attempted to contact the Vendor's Customer Service Website that's listed by Amazon, but the link takes you to a "Surgical & Dental Implant" Domain that is for sale! I would like to find one of these that is truly accurate. This is the 3rd one I've purchased (from different vendors), and none of them are accurate! The last 2 were off by .040" ~ .060" each!

Good part price fast shipping

Nicely machined. looks and feels great.... It's just off by 15 thousands... Still usable , you just have to do the math

The micrometer is very accurate. The price was right, the shipping was fast, and I recommend this seller. Very courteous and professional.

It gets the job done. The measurements on the tool are way off. From what I read on some of the reviews I was expecting that so I just use the markings as a reference and then I measure with my calipers. Works pretty good that way. The tool is aluminum I think. Not a whole lot to complain about. It should last awhile. Not professional but ok for the hobbiest/tinkerer 👍

All good

Good piece
