After I had 5 weeks waited in vain for the sleeves and at random from a friend was told that he had long been waiting for the same tubes from the same vendor, I decided to buy some of it and some to cancel the order at Baomin Electric. In retrospect, I'm glad to have done it. Because compared to the similarly expensive models, which I have now bought later at the hardware store, are offered here but of inferior quality. They look at me more as decorative material for ferrules, as useful as ferrules themselves. I have the impression that here was very saving on material. How then to explain the other, very good reviews? Well, I found out that the dealer in terms of deleting uncomfortable reviews far more vigor shows when the delivery of the goods ordered. In retrospect, I have to say, the eternal and futile in the end waiting time not worth the offered quality here at the end of the saved Euro.
