Good product
I use it for homeowner use. I tested a few chainsaws. Seems like it's working good. Having had any issues yet. Easy to use and you can't beat the price.

Time saving
Work on anything with a spark plug much easier to see than a little spark fast way to tell if it’s a plug are a coil used on car trucks Atv boat and a chainsaw definitely recommend

Works as designed, bulb could be better quality, handy to troubleshoot engines.
Works as described but bulb burned out after 2 uses, Accurate when it works, fits as designed, installation is easy, should wear gloves for safety, compatible with any vehicle, garden equipment, etc that uses a spark plug.

Sparkin in style
Works as intended at a great price. I used this after replacing most of the spark components on my vehicle to check that everything was working properly. Pro tip: If your phone has slow-motion video, use it to record the light to see the timing of the spark easily and confirm that its uniform

Junk, avoid at all cost.
Junk. Do not bother. They're utilizing a bulb way too small for the clear enclosure, wrapped in a spring. The excessive space surrounding the bulb and spring wont allow it to stay in position so it loses electrical contact and doesn't work. Absolute crap, save your money.

As expected
Worked well

Low Quality - Didn't Work
Terrible quality. Tried both and neither seemed to work. When removing from the spark plug, the ends fell off the wire. Returned for defective quality.
