This is my second time purchase. Every thing works perfectly. The unit must fit in opposite direction then only works fine

The product works fine outside but after installing to my cycle, it didn't worked. It only started working once you the device by hand.Finally, I have to return the product. Thanks to the seller and Amazon for refunding the amount.

Poor productDoesn't work even after new battery applied.Seller need to check the performance before it's get delivered.Amazon better select A grade seller...
