Does not work with induction motors. This item was suggested and bundled for a concrete vibrator. It only works with routers.

I purchased this to charge batteries on my model airplanes that use an electric motor.  It doesn't work.  The battery draw for charging  is only 1.5 amp so this must be made for really small devices that draw very little power.

It  was my fault that I didn't read that that this order contains ONLY 4 CW motors instead of 2CW, 2CCW motors, but the product is miss advertised and will not work for quadcopters at all. If you use this product 2 of your propellers will fly off because the rotation of the nut holding them on is the wrong direction. Besides the fact that this order is basically useless to quadcopters, 2 of the 4 motors had worn out bearings (you could hear metal rubbing when you turn the motors) before I even tried to fly it. I lost a nut trying to take off my quadcopter jut to see if it would even work, so now I cannot return it. Would not recommend for quadcopters.

Did not work as advertised or described in manufacturer's write up.

I tried to use this switch for a 3 speeds electric motor, It did not work for this application.
The switch might be good but it works only for a very specific application.

If I could give this product a 0 star I would. It is clearly not made for trolling motors. I used it for ten minutes before it ran out. To make things worse you won't find any customer service especially if you try to return it.

I'm upset that Amazon flagged this item as a fit for my '02 Suzuki Aerio. The inner diameter is way too big for the idle pulley bolt it's suppose to attached to; otherwise it would would have had far too much play if I tried to use it. Due to my trust in Amazon, I didn't test fit this on the engine until it was time to start wrapping up the engine repair which occurred after the 30 day window. I got lucky in finding a local Carquest item that fit perfectly. Now I'm stuck with useless pulley bearing........I suppose I can make a fidget spinner out of it -_-

This item was listed on the page as working with the model machine I have; however, it does not.  The product description on the webpage has since been changed to a more vague description of the machines it works with, but I was unable to make a return (the 30 days had passed) even though it had been posted incorrectly when I purchased it.

Indicated it was compatible with induction stoves and it IS NOT!

I checked on the amazon site for compatibility with my vehicle and while it came up compatible-when my mechanic went to install it, he discovered the pulley on the item does not match with the serpentine belt ribs. The belt has one more rib than the replacement compressor has slots on the 'compatible' pulley. Installing this item would over time, cause the pulley to 'chew' off the unused belt rib thereby affecting the design integrity of the belt. Since these vehicles use only one belt-one would think items listed as compatible would actually be so. I have requested a refund on this item and had to have my mechanic order one that will actually fit.  I rated this item as okay because I cannot say it does not actually work, I can say it is not compatible with my vehicle as I was led to believe when I made my purchase.

I bought this to charge and maintain my travel trailer, which is on solar panels.  This device is ONLY for ac current.  You MUST keep it plugged into an ac outlet for it to work.  It DOES NOT WORK and IS NOT compatible with solar panels or wind  generators..

Seller, refuses to authorize a return ... I have been forced to file an A-Z claim in an attempt to return it and get my money back.

This should have been a simple oops, wrong type, return.

This is not what is pictured.  I did a lot of prep finding a stator that matched my connections and this clearly has a pic of what I needed.  However what showed up was a stator with 5 female spade connectors.  It also has a 2 wire pick up where mine was a 1 wire.  My kids were wanting to ride so I cut the ends off and spliced everything into my old connector.  It did work.  I don't know for how long.  I also had to drill out the mounting holes and grind on the pickup mounting tabs.  This was on a hammerhead 150 go cart.  I never realized there were so many options on these Chinese motors.

Stay away from this item. I mounted this on a 250 Quad  l was building and the craft flipped over when l powered up the motors. I replaced the flight controller and now the quad flies perfect.

It will not work on my Evinrude Boat Motor

I had to go to the boat shop and get one that was made for the Evinrude OutBoard.

The boat shop told me that this switch is for a Mercury, so now I have a switch that will set on the shelf and is no good to me.

It should have been stated in the discription that it was for a Mercury Motor!

If your radio does not have "MID" button do not buy this. Item is as described and it might work on the right model of radio. Mine do not have the button to make it work

DO NOT BUY THIS .
Reasons :
1. Item description is inaccurate : The item description on Amazon says this is a 5V 1.5A adapter. What I received is a 6.2V 1A adapter (see attached picture).
2. Item is not legible for return.
