Posting again, anyone have a rec for hose fertilizers? I have this one and it's getting pretty worn out. Was hoping there was a better option before I just buy a new one of these.

Do you guys use these? I have one and I like it but it's not very durable. Is there anything like this but metal? I like the convenience of just dumping the plant food in there and the hose mixes it for me. But I would like something compatible with the fertilizer that is more durable...
