I ordered this tool via Amazon's Gold Box for hobby use (wood ship modeling) - I figured it might be cheap (or at least, very inexpensive) junk, but more accurate than I need for the purposes intended. However, from the moment I first opened the case, I was extremely impressed with the tool.

The quality of manufacture seems to be very fine - good "fit and finish," with smooth operation and crisp button response. It has a *solid* feel to it.

The performance is far better than I expected. There is an ON/OFF button, but the gauge turns on automatically when the calipers are opened, and turns off after a period of inactivity. There's a button to toggle between inches and millimeters as well, but more interesting and potentially useful is a ZERO button, which allows the user to set any particular measurement point as the zero from which the next distance is measured. Nice.

The repeatability also seem to be quite good - I tested several times with some machined brass bars, and the measurement was accurate and consistent.

If I had to say anything bad about this tool, it would be with regards to the extremely weak documentation that accompanies it. For instance, it does not accurately describe how to open the battery compartment with the included screwdriver. Indeed, the illustrations in the "manual" are of a slightly different product... but then, if you are the kind of person who buys calipers, this is not a significant obstacle to overcome.

I don't know if I'll ever be able to wear it out to the point that it needs replacing, but I would buy again.

I'm happy with the tool. Just be sure to have a new LR44 battery on hand. My tool arrived with a dead battery installed and an extra, albeit already corroded, battery.

First impressions are the most important. In the case of this digital caliper, that's unfortunate.

See the two attached images showing the entire Owner's Manual. It consists of one page printed on front and back and is for a different caliper. One image shows 2 screws on the front of the battery compartment. On the actual digital caliper, the screws are located on the back, side by side. The deep-well screw is for the battery compartment. The shallow-well screw removes the wheel and retainer. The Owner's Manual does not show this. Also, the battery inserts the same as in most watches with the positive (+) side facing out. This information is not included with this caliper, but it has been with every other quality digital precision instrument I've ever purchased.

The impressive product description on the product-information page sold me. However, none of this enticing product information is included with this caliper. No where on this caliper or in the Owner's Manual do the words Titanium or Stainless Steel appear.

I have two quality dial calipers. Both have "Hardened Stainless Steel" engraved into the metal just like the caliper pictured in the Owner's Manual.

With this digital caliper, it is left up to the consumer to completely trust all of the information listed on the Amazon.Com product page. In the past, I have found the product descriptions of other items made in China not to be entirely correct. I like to see important features like high-quality metal either embossed, engraved or included in writing along with the product.

The next thing I noticed was what seemed to be a slight bow in the scale bar. I measured it to be .050" or 1.27mm along the length of the scale. Luckily, it did not affect the accuracy or the movement of the slide bar. This suspected flaw might very well be designed into the tool for some unknown reason, but I seriously doubt it.

My other dial calipers are perfectly straight.

I tested the accuracy using brass objects of known dimensions and also against my dial calipers. All were in harmony. This caliper is accurate. It feels solid and is polished. The only blemishes and nicks I found were on the ridges of the deep well housing of the battery screw.

The plastic snap-shut case is durable and the shaped-foam interior affords adequate protection.

I will get good use out of this instrument. In many of my projects like reloading or clock work, I double check every measurement using two different calipers. Accuracy is the most important feature, however, this caliper is not 5-star precision quality.

Note that the minature phillips head screwdriver
(included in the case), is needed to remove the screw
that is securing the battery cover.

To remove the battery cover, flip the caliper over
to the back side. You will see two screws. The
screw on the right is RECESSED and is the screw that
is securing the battery cover.

The screw is very small and could be hard to find
if you drop it or let it get away from you.

So far the device feels very solid and well worth the
$27 paid...

I have only used this caliper for a couple of days, but so far am very pleased. The button have good solid feel when pushed. I was worried that since the on/off button feels so solid that I would have to remember to turn it off after every use,but it does have an automatic shutdown after so long. The large screen is extremely clear and easy to read. If this one holds up I would definitely buy again.

This micrometer certainly works for me. Opened the box, zeroed it out, measured a standard piece of printing paper, 4 mils. I believe exactly where it should be. Even better that I got it as a "today's deals" at ~$27. Now that I know what it is, I'd pay more than that. Hard to go wrong with this micrometer.

This caliper replaced one that didn't have a screw to secure the battery compartment causing a loss of contact. So far I have not had a problem with this caliper. It comes with an extra battery, screwdriver for the battery compartment and a nice padded case.
there is also a scale on the handle which comes in handy.

This micrometer is a high-quality, very accurate instrument that measures inside and outside dimensions and hole depths from very small up to 6 inches. I use it mostly to measure gemstones so that I can calculate a rough approximation of the gems carat weights. Sure, you can pay less than half of the price of this caliper for a different 6-inch caliper if you don't mind having one that's less than half of the quality.

Have to say, been pleased with this product. It works great, very solid, like the extra battery included along with small screwdriver and foam pad hard plastic case. Using it to measure small but strong magnets. The titanium and overall design feels very solid. Easy to read quickly the digital display. Really using the Metric to SAE Inches alot, since we need to convert our measurments quite often. Great for measuring all 3, magnet depth thickness, magnet length & width, and measure how wide a tube is inside. Recommended micrometer caliper. Better to pay extra for this quality, use of titanium.

As with others, I could not figure out how to insert the battery. The pamphlet is wrong and of no help.

I am thankful for reviews which helped me with my problem. The last thing I wanted to do was to try to force the cover open.

Solution: turn over to back side, remove deepwell screw, insert battery plus side up.
