Unfortunately, no good word left

Have I bought these lights and also the reviews to read before buying.
Nevertheless, I bought 2 pairs of the same so that I at least some cheap lights on the wheel. But these lights are so poorly handled that just suck anything. After the first use both taillights have stopped working properly. I had to repeatedly press to turn on on the button and have it then just anbekommen because I've removed the lights from the wheel. after one week she no longer went.
My advice: spend Lieber 5 euros more, because these lights are just plain junk.
And the shipping when you return the items you have to pay for it myself!
