I ordered two pieces and have to say that in both the cogs were not easily adjustable and therefore adjust at least for the two accidental, as a previous speaker said, can not happen. but the wheel can also be not too heavy disguise, so that the handling is quite comfortable.
I also have yet not dazzle the sticker found, but this could be because of the scorer is attached to my bag and I this herziehe mostly behind me. However, these two stickers fall off partially light, which can be remedied by some glue easily but.
I would recommend this product Recommend.
