Review on DAWAY A08 Bike Tire Valve Stem Light - LED Waterproof Bicycle Wheel Lights for Cool and Safe Night Rides - 1 Pack/2 Pack by Mark Jefferson

Product poorly designed. To insert the batteries, the battery compartment must be opened by unscrewing the block. When you unscrew the device, you may see that the plastic male threads come loose due to the metal female threads. So now the plastic threads are frayed from unscrewing the device, you insert the batteries and now you try to twist the device again and the plastic threads don't want to screw onto the metal threads, then I finally assembled the device. , and believe me when I tell you that it took a lot of time and perseverance because when I finally assembled it, the device didn't work because of that little metal wire that was supposed to be in contact with the battery and it didn't work Doesn't work so I had to fiddle with it a few times which also meant dealing with endless frayed and worn plastic threads, at least I didn't have to unscrew the device all the way to fiddle with the contact wire thank goodness. Well, through trial and error I finally got the device working, but I'm scared of the day I have to change the batteries, the plastic thread won't hold up another battery change, then I had to be very careful screwing the device into the Bicycle. Tire stem valve to not turn the threads of the block because it will ruin the contact wire thing, and then it goes back to the drawing board. No quality control and no annoying need for the user to go back to the drawing board. But I have to say that now that I've got it working I love how the device lights up. I'd like to buy a second device, but it's poorly made and I don't want to mess around with another one.
