I doubt my motor reaches 8k or 9k rpm, buuut I will say it works amazing, no hesitation I think I have my adjustment around the coil wrong. Been messing with it for half a day so far I love it. For a mini bike 224 max performance and aftermarket flywheel, springs and sparkplug, throttle linkage, no governor.. etc... first time building a motor like crazy and I'm loving every part I have bought so far, highly recommend this tach if you are looking for a budget purchase. Just adjust the wire coiling correctly unlike myself LOL

So, I bought 2 of these units to install on each of my 1930 Ford Model A's. Are they 'period correct'? Nope but just lid Dragnets Joe Friday.....I just want the Facts! And these are great! Less than 10 min each to install and I really like the 'hours' of running time as well as the Tach function. Just what I wanted and needed.

Works well comes with zipties for coil wrapping around spark plug wire. Doesn't shut off unless you press both buttons simultaneously. Has basic instructions for 4 and 2 stroke. Can't beat for the price.

I installed it on an older outboard for my pontoon boat. It provided the information that I needed. Easy to install, you may have to mess around with the settings so it reads correctly. I’d recommend this.

I installed this on a Kohler CV-490 1 cylinder engine and the rpm reading is incorrect. I tried changing the amount of wraps around the coil plug and changing the settings but nothing fixed it. It does work fine as an hour meter but as a tachometer stay away.

Easy to install was the highlight of this product. The accuracy and functionality is a huge miss. No thank you… choose something else. Guess the saying you get what you pay for is truth in some cases. Spend the extra money and get something reliable.

Bought to monitor rpm whilst adjusting carb pilot screws. Worked OK. Battery is not replaceable so don't think it will be working after a few months, but to be fair it was a budget price so I would be happy to purchase again if necessary.
