Died after the first rain.

Works as advertised. Until the first rain. Then the whole body was filled with water inside and the device stopped working. After drying, the device worked for about a day and died out. I wouldn't recommend it unless your boat is stored indoors and the tachometer is mounted under a cover.

Pros
  • Easy to use
Cons
  • Long delivery time

Must have a bad block that kills batteries fast.

Installed, looks smart, 2.8 volt battery after switching off the device after 0.4 hours of operation. (should be 3.3 for a new battery). Installed a new battery and it ran for about 0.5 hours before dying of battery during use. I must have gotten a bad device. Long time no bought and can not return.

Pros
  • New
Cons
  • Little things

Don't get him wet or feed him after midnight.

Product worked immediately after installation. I used it mainly for diagnostics. In heavy rain, the hull filled with water. The touch stopped working after 2.7 hours of operation. I want to get a replacement but there is no way to contact the seller. I think this review will stand until a replacement arrives.

Pros
  • Robust design
Cons
  • Almost everything is fine

Definitely not waterproof or waterproof!

Despite claiming to be "waterproof", the device absorbs moisture, causing the screen to fog up from the inside. I installed it in our boat's enclosed engine bay, flushed the engine bay (no direct water on the unit), and within 30 minutes the display had fogged up from the inside. Hoping that a day in the sun will dry up.

Pros
  • Sleek design
Cons
  • Some issues

Too disappointing to justify the price.

Don't waste your time and money. Don't listen to those who say everything works. It's good at reading RPMs, but that doesn't matter. There is no on/off switch and the battery is very difficult to remove. It's in a deep pocket and cozy. If it's not functional or practical, then who cares about the specs. Save yourself the hassle. Get one with a switch!

Pros
  • Price
Cons
  • Some little things
