For the price, the product cover is just fine. However, the "stress" when turning up or detection on the lens threaded through two small ridges is generated. For me these are already jumped out the second time. These are fairly small parts that are merely inserted into the edge of the lens hood. Happened one in the "area", they are probably lost immediately and the lens hood is unusable. Can eliminate the problem is with two small drops of seconds or plastic glue each on one side of the two webs on both sides of the lens hood. While this does not win a beauty contest and is a bit tricky, but the lands no longer go out and the hood holds - even after months. For the panel speaks the otherwise good workmanship and the subjective "exactly right" resistance when turning in and out.
