Transparent tube is hard and handling is very bad. Also, the junction between black parts and tubes is easy to come off. If you hold only the tip, the handle of the vacuum cleaner to be connected is heavy and the joint part will be pulled out quickly during cleaning, so with the possession of the vacuum cleaner, with the tip, and the tube is further routed ... It is noctrone. Other parts are OK. There was something that also fitted the connection port size. I could not put on Dyson.
