    Works good, low price, feels a little 'plasticky'

    Simple to use, just turn it on, and point it at the shaft/wheel/pulley/sprocket you want to check the RPM on. It needs some sort of reflective surface to read, so you can either polish off a small spot on the pulley or whatever, or you can stick a small piece of reflective tape, and aim the tach at it. The reflective spot only needs to be about the size of the nail on your pinkie finger to get a reading.To test accuracy, I compared it to the tach on the dash of my pickup. They read the same, but it takes this one a little longer for the reading to stabilize, making me think this would be best to check something with a fairly steady RPM, and not something who's speed constantly varies. It does what it says it will do, at a bargain price, but it feels to be of only average quality. Pro versions feel much more substantial and solid. I doubt they are any more accurate, though. Turn it on, aim, and it reads out the RPM. Has a recall button to bring up the last value shown... 4/5 J. Bruha (Nebraska, USA) - See all my reviews, September 27, 2016

This review is from: CE Compass New Digital Laser Photo Tachometer Non Contact RPM Tach (Electronics) I read the bad reviews and the good reviews and decided to take a chance. All I can say is I must have gotten a good one! It works quite well. As to accuracy, I have nothing to compare it to, so I'm going to assume it's close, and that works for me.

    Would be higher rating if I didn't have to fix it first.

    Was not in a condition to work right out of the box. The device was still in shrink wrap so it was not a return, but it could not provide a reading first time I tried to use it. I work in optics and could tell right away the problem was with the lens assembly because it was loose and out of position. I was able to fix it quickly and then it worked like a charm. If the initial quality was high I would give it four stars. In case you take the plunge and also get a lemon, here is what to do:Remove the battery cover. There are two small black screws recessed in holes that need to be removed; use a skinny Phillips head screwdriver to remove them. At the opposite end there are two more screws also recessed. When those are out remove the top cover. The two push buttons may fall off their switches but don't worry, just set them aside. On the top of the circuit board near the lens you will see a clear photodiode; mine was bent at a severe angle. If necessary use your... 3/5 Michael Morris (Santa Rosa, CA United States) - See all my reviews, July 2, 2016

    Huge Dissapointment

    1/5 Airplane Driver (USA) - See all my reviews Verified Purchase(What's this?) This review is from: Neiko 20713A Digital Tachometer, Non-contact Laser Photo | 99,999 RPM Accuracy (Tools & Hardware) Bought this to cross-check the tachometer in my airplane. I attached the reflective tape on the backside of the propeller which is painted mat-black. Ran the aircraft on the ground and held the digital tach at various distances from the back of the prop and just could not get a reading that made any sense whatsoever. The readings were off by orders of magnitude and clearly were not right. I tried different speeds, different locations for the tape and different times of day (to eliminate the potential for backlight issues). Nothing worked.The written directions are really horrible. You would think that a company that markets products in the US would have engaged someone that can speak English to write the instructions.Anyway, I don't know if I got a defective unit or if it is just junk....mine did not work at all and I returned it.

    Good for getting approximate RPM

    This device works great if you are working in the 1000+ RPM range. I found it struggled to give good readings with slower RPMs, especially in the sub 100 RPM range. I would have expected the accuracy to be a little better in the lower range since the product description does state that it works for "0-99, 999 RPM". However, it did allow me to get in the ballpark of where I was looking for in finding the RPM of the parts I was looking at. One thing to note with this, if the surface you are attempting to measure is reflective at all, you'll get a lot of bad readings. You have to find some way to eliminate the reflections so that the only reflective surface it is reading is the tape that you place on it. This is really to be expected because of the method of measurement, but it seems important to note. The surface doesn't have to be mirrored, I was having some issues with this on some slightly glossy plastics. I found that a coating of baby powder often did the trick, but... 4/5 Julian Rodriquez - See all my reviews Verified Purchase(What's this?)

    Good addition to my tool box.

    5/5 Hugo T (Ca) - See all my reviews This review is from: Flexzion Digital Photo Laser Tachometer Portable Automatic Non Contact RPM Tach Gauge of Motors Engines and Machine Parts With Accuracy 99,999 Measurement LCD Display Carrying Bag Arrived well packaged also has a solid feel to the meter. Since I do not own any other Tach meters there is no way for me to compare the accuracyof the meter. For testing I used a cheap USB fan. How it works is by first placing a strip of reflective tape to the fan blade, as the fan is spinning point the laser at the reflective tape for a reading. My testing was done with the meter 2" away from the blades. My first test I used two pieces of tape one on the fan and got a reading 4618 rpm. Before taking my second reading I went ahead and sharpie out one side of the reflective and took my reading of 2361 rpm. I expected the second reading to be half of the first reading and it sure came close at 52 rpm difference. Based on the testing method I had used I find this meter to be accurate. The only thing I found that may become an issue is the battery door feels really loose and can fall off easily. I purchased this tool at a discounted price in return for my honest review., October 2, 2015
