On the plus side, they are as cheap as a ruler, and measure much better than a ruler. Take the battery out after every use if you don't want to replace it next time.
Having said, that, the out of the box performance initially gave me a scare because every time I moved the digital reading head along the bar it gave me a different reading. After reading the instructions, I discovered that the bar had to be cleaned before using it. After cleaning the bar as instructed, the caliper gave me consistent reading at least five times in a row as I opened and closed the caliper to at least 3" and closed it to get a 0 reading. I am glad that I did not throw the instructions out before reading it like I would usually do.
-The slide is so gritty that it has made the thumb slide unusable simply because the action is gets stuck.
-I often find that when the jaws are opened and closed the measurement reads a value close to 5 mm instead of 0.00 mm. I can't seem to determine how this happens as it does not seem to be tied to how quickly or how far the jaws have been opened.
-There are some major scuffs and scratches on the slide, the display and the jaws.
-The Inner jaws do lot line up on the pair I received.
-The outer jaws have substantial play.
I could have just received a poor example but I am heavily disappointed and will be returning this and trying out a different pair.
After doing a bit of searching online, I found where my coworker had bought it from. Here! I had expected something like this to cost double or triple of what I actually paid for it. Shipped to my house, it was $11. It comes in a plastic case with an extra battery and instructions.
I can't begin to say how useful this device is after buying it. It measures three dimensions: Inner diameter, outer diameter, and depth. I had a set of car tires I was trying to sell and this caliper aided me in accurately measuring tread depth. I was able to accurately list the % tire remaining, which helped sell the tires. An $11 tool got me $200 sale in tires.
They do sell this same caliper at Harbor Freight, and I've seen it on sale for $9.99, but with tax and driving, its cheaper to buy it here.
No issues really. The slide was a bit stiff, but a drop of oil solved that issue. Excellent quality and an exceptional price. Don't hesitate to buy this.
The machining is clean and precise. It looks like a quality tool. It turns on automatically when adjusted and remembers its zero reference and scale, inches or metric. I did not yet test the auto OFF but assume it works. The battery in the caliper appears good. It does have an additional battery. The case was better than I expected. It is solid plastic of respectable quality and has only a thin sponge padding under the caliper which I prefer to a thick one.
It probably would not standup to being used as a hammer and if you throw it in a tool box full of tools it might break the plastic “computer” housing or LCD but I would not try either with a precision instrument. I am very pleased I could buy a caliper as good as this for $11.
