I bought the new one with the rubber corners on it last week ready for larford last saturday. I threw it in and it sank right away no problems.
I also used it again sunday and sank again on its own I didn't have to push it down with my landing net handle like usual.
Dry's out fairly quick too. The locking thing at the top is good too.
I have only used it 2 times though but so far I'm impressed.
Will prolly get another in a few weeks.
4 meters , bloooooody hell. I have the 3.5 meter and it takes half an hour to pull in
