I bought this for my gal because we already own an E-845 without the switch, but she liked the ability to turn it on and off. They connect quickly and consistently. This product is easy to install and looks great. It is noticeable. Ill never buy anything else. Nice roomy bag; however the material is really flimsy and if you remove your racquet the other items in the bag shift so that you cant return your racquet without rearranging everything. I speak to Alexa to trigger all lights on. Its made in China, so that should tell you something. The wire support is heavier, plastic thicker and clearer and most importantly its the right size. The straps it comes with really hold it in place.
