I bought this particular tachometer, because I own several tools made by Neiko, and they're quality tools. I used it to test my new 1.5kw spindle motor and vfd.It's important to use a small piece of the reflective tape on whatever you're testing. The tape wasn't sticking well to the spindle motor, because of the packing grease. Even after cleaning the collet chuck, it came off. So, I put a piece of non reflective tape on the chuck, and a small piece of the included reflective tape on top of it, and it's still holding.It was with the Neiko tachometer that I discovered that my new vfd display wasn't defaulted to rpms. That sounds like something that would be obvious, but my vfd reads out "r" before frequency, not rpms, so I thought r240 was 24000 rpms; it was a frequency of 240 (go figure). When I realized what was going on, I was able to correct the vfd programming so that it defaulted to rpm readout. I found that the vfd was correct to minus 35-50 rpms. The Neiko reading was rock solid, and consistent through 6 different spindle speeds. I didn't find a difference in reading based on distance from the source; the reading was the same whether taken 4" away, or 4' away.It came with a battery, which worked. But, I prefer a good alkaline battery over a mercury battery, so I'm storing it with a 9v alkaline. I do not store my battery operated tools with batteries inserted; I store the batteries with them, but not inserted.The storage pouch is nice. I'm storing the tachometer in the cnc table drawer. The neiko tachometer came with a zippered pouch, quite a bit of reflective tape (I'm only using about 3/16"), a 9v battery, and instructions.

This is exactly what I was looking at and I didn’t have to empty my wallet. I put a new 5-step pulley on my drill press and there is no tag on the head to state the speed at the different belt positions. I test this on my lathe that already has its own tachometer. The two matched up very well at a variety of speeds

So far so good. I put a piece of the reflective tape on the drill chuck and gave it a test. Handheld tachometer is within one RPM of my drill press readout so I am happy.

Overall this is not a bad product considering the low price. As others have noted, installing the batteries is no easy task! I did not use the cheap carbon batteries provided, but used name brand alkaline batteries. It wasn’t easy to get them seated to the point where the battery cover could be properly closed. Also of note; the battery cover does not slide off, as stated, until a small screw is removed.The accuracy seems to be reasonable, although I doubt it is as accurate as the specs state.Unfortunately, there is nothing special about the reflective tape provided to attach to the shaft being measured. It’s just shiny, which means you cannot measure the RPMs of a shiny shaft! The instructions say to cover a shiny surface with black tape or paint it black!Luckily, on my lathe, the shaft just behind the chuck mount is black, so the shiny tape worked fine. See the attached photo. The chuck on my drill press also has a knurled black band on it. The problem is the tape provided won’t stick to it, so additional adhesive was needed.I had hoped that the reflective tape would be somewhat tuned to the internal laser so it would work on shiny shafts, but I guess that’s too much to expect from a product that sells for less than $30.

Have not used yet

Very good i like it

Purchased this to verify the fan speed on a AC condenser. Shiny 3 blade fan.....read the RPM.....divide by 3. Had my answer in less time than it took to put the battery in. BTW.....the fan is rated for 850 rpm.....this fan is running 860 rpm. All good.

Works well, best to use reflector tape.

easy to use, seems to be accurate. used it to set speed controller for a generator and the frequency was almost spot on.

I was a little skeptical about this tachometer considering the price but after a fair amount of research this brand did get really good reviews so I decided to give it a try. I tested it against a fairly new JCB 4 cylinder diesel engine with Factory digital tachometer to see how accurate it was. I tested it at 1000, 1500, 1700, and 1800 rpms. and It was dead on across the board! I'm very impressed. The next time I need another diagnostic tool I will look to this brand to see what they have to offer.

Works awesome Used it to set the idle on our Mitsu

it works, was able to measure rpm of my condenser fan.

Easy to use,

Works as expected

I used this to test my turntable and wood lathe. It does the job.

Works great on hyd pump shafts

Works well and comes with a nice little case that holds the device.

Nice product works well

Easy to use, read, and for the price it's hard to beat.

Got this for grandson so he can get the rpm of the motors he builds and he loves it

Does measure rpm. No complains

used to very my milling machine speedthe supplied reflective tape could be "stickier" but it works

Purchased to check propeller rpms on my RC motor test stand. Indoors so lighting was led shop lights but that shouldn't matter because the unit has it's own red led built in. Worked great on wood or black nylon props but seems unable to "see" the grey APC style ones. Perhaps a black sharpie might help. Also, store with battery removed. It appears to have an auto shutoff feature but mine killed the battery after 3 or 4 days of my not being aware it was on. Works great as best I can tell though!

Unit appears to work well. Comes with quick instructions and some reflective strips (I bought extra, as well). The case it comes with is very poorly made, though (mine has split seams right out of the box), which is why I knocked off a star.

It works well and is easy to use. If the disc is speckled though it can give an erroneous high reading. It drains battery when turned off so if you are not going to use it for a while remove the battery.

Well, please with it I borrow it to Check thing on my wood leg whether it was running the same speed as my meter it worked really great for that. I think it’ll work well for what I do.

Works well with no issues... Seems to be a good quality product. I do recommend this unit!
