AIMILAR Wireless Vibration Hour Meter - Waterproof Hourmeter for Gas Diesel Engine Motors Lawn Mower Air Compressor | Tracks engine hours via vibration, no wiring, battery powered, waterproof construction for maintenance

I wanted to know hours of operation of a heater and research (incorrectly) indicated that this device was senstive enough to do that. It's not. Works fine where there is a reasonable sharp tap or vibrate but needs more that my fan motor does.

Great hour meter. It's setup is 'interesting' as one has to 'cut' a wire in order to activate it. (I guess that's not a bad idea!). The vibration sensitivty is advertied as most sensitive when mounted face up. That's how I used it. I'm using it on my PCP high pressure air compressor. Actually, my compressor does not vibrate too much, so I was initially worried that this would not pickup the vibrations. It did. Impressive. The only comment/complaint I have against this is: The instructions advise the user to either use 'double sided tape' or 'screws' (which are included) to mount the meter. The screws are included. The double-sided tape is not. Good thing I had some on hand. I do like how it reads hours in 1/10 of an hour (i.e. standard decimal notation) instead of trying to display HH:MM. Anyways, great meter, low cost and does the job!

I bought this item back in 2024 for my mower. It is now on its second year, and , does not work anymore. Trying to return for the warranty of 2 years. Hopefully i get one. The one with the wire to the spark plug wire works much better

Great product, functions as described. Happy that now I can accurately track usage on my mower.

I got the Aimilar timer for my 30-gallon air compressor to help me keep track of oil changes. Read on for our evaluation -- MEDIUM SENSITIVITY WORKED FINE: Since the timer has to be installed vertically, it's in the medium sensitivity mode but did not have a problem sensing the air compressor pump running as shown in the video. -- MOUNTS WITH 2 SIDE TAPE: The back of the unit is not flat. So I had to use 2 layers of foam 2 side tape to make sure it held well to the air compressor pump. I used 3M foam 2 side tape to attach the face of the air compressor pump. -- PROVIDES VIBRATION SENSE FEEDBACK: The timer worked well and sensed the compressor running and there is a small area of the display that activates when the timer is running to give you some positive feedback and it working. -- NO TIMER RESET: It would have been nice if it could be reset, say at the oil change, but there is no ability to reset the time that I can read anywhere or find on the device. -- INCOMPLETE PACKAGE: The delivered package had a large empty blister meant for something but it was empty...not sure what that was about ....maybe a screwdriver? -- NEED TO SNIP THE WIRE LOOP: Luckily I read the instructions as you need to snip the wire loop for the unit to activate. -- OPERATING LIFE: The webpage says it has an operating life of 2 years and I'll report back especially if stops sooner than that.
