Works well

Nice product for the price but AVERAGE function does not come on, otherwise I would give 5 stars

Easy to use and read, reasonably priced. Has all the accessories you need for various measurements plus a nice case to store the instrument and accessories. Pleased

Bought in June 2025. It did not work. Powered up but did not measure and read. Did not function at all other than turning on. Coworkers bought as well and the tips are cheap plastic with no friction to hold onto anything and come off easily. This is cheap garbage. Don't waste your time. Even when coworkers bought one similar style to this, very poor lifespan...(as expected for the price tho). It should be easy to use, but seeing that it doesn't read...couldn't use it at all. Could be problematic showing up to a job with a brand new nonworking tach. Saw a similar review for other tachs purchased mid 2025. Save your $40 this is a waste.

For non professional use perfect tachometer

If all you are measuring is RPM, this tool works well. ANY other measurement, especially Ft/Min requires turning on the device using 2 buttons and then a set-up of another 6 or 8 buttons to get it to work. Then when it turns off you have to go through the whole process again as it does not save the set-up. This will require your workers to take out the booklet and figure it out every time if they only use it once in a while. NOT intuitive.

The Best part of this device is that it is easy to use.

I needed an accurate tachometer to set the RPMs of an engine powered pump. I had an old analog (dial) one that started giving erratic readings, so I thought I'd try this one. Simple to use, just turn it on, and read the RPMs, and it 'holds' the latest reading on the screen for a few seconds. You can also set it to read things like maximum RPM, and with the right accessory, can even read linear FPM for things like a conveyor belt. My biggest nit to pick, is that it seems a bit delicate when compared to my old all-metal one, especially the tips that engage the shaft, (old one was metal with a rubber tip, this one is plastic and also smaller) but it has worked well enough. For the couple times a year I'll be using it, it is fine. Came with a carrying case that keeps all the pieces together. I got this one because it had an extension for the tip/shaft to be able to engage a shaft within a recess, and I'm glad I did. With the regular tip and no extension, it does not have a lot of reach.

Excellent product for the money! Excelente seller!

周速の測定メインで検討し、測定リングの延長バーが付属されていたことで購入決定。周速表示では表示の更新周期が少々早く、値が読みづらい気がするが値段からすると機能は満足できるレベル。付属の周速リングは消耗品だが購入できる？。小野速の周速リングは微妙に大きく、ガイドのスリットも狭くて、そのままでは使用不可。しかし自己責任の加工を多少行えばいけきそう。

Ben fatto ma forse un po' troppo complesso da usare e un bel oggetto speravo un po' più semplice invece ha tantissime funzioni che non so neanche se userò consiglio perché e un bel prodotto e di ottima qualità

The one I received did not work at all. I’d also consider the method of measuring suspect as it has several friction wheels and the variance of diameter between the friction wheel and the item being measured will mean the rpm will need to be calculated. As the one I got did not work I did not have the opportunity to test this out.

10センチ仕様のホイールが、実際には10.5センチあり、速度を正しく測れなかった。所詮中国製だった。お気をつけください。
