Check Engine Light Flashing But Car Runs Fine

I purchased this light to help me with engine inspections on my antique car. It's a well made light and emits a great circular shaped beam of light. I have Coast batteries that work well with it.

Exactly what it states it is. Runs a 700 Hz tone to check lines. It is working fine for us.

Very good device but hardly fast speed and external light keep flashing green. But over all everything seem fine

but it is unsettling to have the upstream light flashing

i use this with a 2 in 1 tablet computer, very portable. Runs on usb power, flashing LEDs tell you it's connected and talking to your devices. does not seem to lag, works well. fits well in gig bag with keyboard

[This review was collected as part of a promotion.] I used this to prank my sons to think I actually blew up the engine in my car. It looks so realistic I can’t wait for my favorite holiday Halloween to help in decorating my house.

This thing is great. I can clamp it on my handlebars, my engine guard, on the half open car window, anywhere. It's the do everything GoPro accessory.

These are one of those innovative products that help you save money over time. Long gone are the days when you have to buy air cans! That in itself should pique your interest!I live in an area where dust is very prevalant. I recommend using this product for when you want to remove dust and lints from various nooks and crannys.The 500W motor (0.75 horsepower) which produces 70CFM amount of air flow is more than sufficient for everyday use. I have yet to come across a computer where this was not enough power.Aside from just cleaning electronics this duster really helps keep my engine bay clean, which is where I use this duster the most. My cars engine bay has many areas where debris like to gather. It becomes difficult to reach some of these areas with my hands as it is very tightly spaced. This is where my duster does its job (well). Using the thin nozzle attachment I can blow away little pebbles with ease.I also love the fact that the material used to build this duster is durable and well made. It doesn't feel cheap in your hands at all.I have noticed that the duster can run hot when used for a long period of time or when you use the thin nozzle attachment. I guess a bit of stress is put on the motor as it is trying to push a large quantity of air through a smaller diameter/area. (a phenomenon that can be described with fluid mechanics, which I couldn't tell you because I've forgotten all my physics!) In any case, I simply turn off the duster for a short period of time to cool it off. It does impede in the dusting process but it's not a deal-breaker in my opinion.This duster is also useful for when you clean and detail your car. After washing your car, use the duster to blow away excess water and to remove water from the side mirrors so that they don't drip while you're cleaning your car!Metrovac is known for their quality parts and they did a great job with this duster!

This is one of the better glass and lens that I have had.. and the interaction with the Sony a7rii are tuned together as a fine tuned engine. Very happy with it

It works just fine. The use is very intuitive so I did'n have to check instruccions.
