Electronix Express 0604CAL6++ LCD Digital Caliper with Extra Battery and Case, 6"

This (at the time I bought it) is a $12 caliper. If you have extremely exacting needs stop reading right now, it’s not for you. Please don’t buy it because it’s cheap and then complain that it’s cheap, that doesn’t help anyone else make an informed buying decision.If, like the vast majority of people who have a casual need to measure the outer, inner or depth size of something occasionally … this is perfect. It is actually a truly astounding value in terms of build quality, materials and usability for the price. If you’ve never owned a caliper, you will probably find uses for it around the house that you never dreamt of. Almost overnight it has become one of the most useful tools I have.I won’t go in to one word of detail about how this caliper “fails” compared to a $100 tool, or how for only a few dollars more another brand may have some miniscule advantage. At the time I bought this it was not only (by far) the cheapest digital caliper tool at Amazon but it was also their #1 seller. Duh.The look and feel is one of precision. There are no loose, sloppy-fitting parts. The display is large, clear and easy to understand and turns on automatically as soon as you move the slider. The controls work as expected. The included case acceptably protects the tool when not in use. A pre-installed battery and another spare battery are included. The user instructions are adequate even for someone who never used a digital caliper previously.I can’t possibly think of any reason I would ever need a caliper that is any more precise than this one, but if I did I would have known that before coming to this page and choosing this one. This is absolutely a 5-star bargain.

I bought the product thinking that it would work for a little while and would be accurate within a millimeter or twosince that is all I needed and it was cheap. When I received the product the display randomly changing numbers, but I thought it might be because it was cold from being left out side by the delivery person. After leaving it at room temperature for a few hours it started to work better. I was able to turn it on and zero it out without the numberschanging. After about a minute though the display starts flashing and then the numbers will start randomly changing again. This is the worst caliper I have ever seen and I don't know how they could have done such a terrible job in building it. I would not recommend this product to any one even if they needed a caliper for just a one time use. If you plan to use a caliper often or need a quality one then I would recommend spending the money towards a good $40 one.

I was expecting something low quality given the inexpensive price of this product, but I was pleasantly surprised. The first thing I noticed was the case. Though it is made of plastic, it does not feel flimsy or cheap, but is strong and surprisingly heavy. The case opens easily but seems to latch securely. Inside, the caliper is surrounded by a high density foam (again, nothing cheap) that seems like it would really protect the product.An extra battery was included, as well as the pre-installed one. I wasn't really looking at the buttons and just started turning the little wheel and to my surprise the display came on. It appears that if the caliper is moved it turns on automatically. The wheel is nice as you can move the calipers very precisely with it, however it is not meshed- that is, once the calipers hit even a slight resistance (from the object you are measuring, presumably), the wheel spins in place and the caliper no longer moves. I suppose this would be great for measuring something soft, but if you want a bit of clamp down a bit on the object while it is being measured, you will have to push the caliper directly.There is both interior and exterior measuring capabilities, and the caliper can be calibrated at zero wherever you want. It will even measure negatively. I can see this being quite useful for comparing sizes. For example, you measure an object and calibrate at zero with the object. Then you measure another object and the caliper will read the difference in size between the objects, positive or negative. The readout give a measure accurate to .0005 inches or .01 mm (although I did not test this accuracy).In short, I would definitely recommend this product, as it seems a great value for the price. In fact, I almost feel like ordering a few more for myself even though I would have no use for more than one. Don't waste your money buying a more expensive product- this one is just as good.

Based on some of the low numbered reviews I felt I was taking a chance ordering this, but have been quite pleased with it. For the price it's a very nice tool and is a good value for the money.I should mention that I received no spare battery. There was no battery in the tool and only one in the case. Not a big deal, but a bit disappointing.The tool itself is well made and well calibrated. I have tested against several known size devices and have gotten precise readouts. I have not encountered and of the rough or sharp edges mentioned in other reviews. Everything is smooth and moves freely. The measuring edges of the caliber faces are a bit sharp, but they are supposed to be. That's part of good tool design, precise measurements require a knife edge at the measurement surface. Both the printed scale and the digital readout have provided consistent, quite satisfactory measurements.It works like it supposed to and so far has not given me any problems. It's not designed for the 24x7 use cycle of a precision machine ship, but for most contractor or home handyman occasional precision measurement needs, its just fine.
