I bought 2 extension tubes, one for immediate use and one as a spare. As someone mentioned, they seem expensive for plastic, but that's not the case these days. When you need them, you don't have a choice, do you? One tube I opened fit snugly so I was happy with that. I have not opened another spare part, I hope the same one fits. Some reviews said they were loose, but when I bought my new filter one hose was tight and the other loose; I just thought I'd mention it. These tubes were as I expected. I was wondering if the dark gray tubes would look weird with this clear tube, but then I noticed that when I put the new one in with the old tubes and they got wet, the clear tubes turned a darker gray than the other old tubes. (Same color as the filter flap.) They arrived undamaged; survive shipping in a bubble envelope. Thank you Revain for the great transaction and shipping! Very happy with my purchase and would buy again anytime.
