To get a prospective of reality and not turn this into a commercial perhaps its best to say what nets have let you down, and those that have not.
In my experience nets last a long time if not abused.
My nets since I started,
I still have my original circa 1954 aluminium 18" folding net frame.
My original alloy and steel 42" Efgeeco Pike net, old knotted mesh replaced.
Hardy Sea Trout net with the wading pole handle and original knotted mesh.
Fastnet Pike net professional model (landed more fish than I can count but still perfect).
2 off Middy 22" latex pan nets, of which the round one lost both screws from the spreader block.
I have never had a net or block break on any of the above nets and all are still available for use except the antique which has been retired, .........like me
