Never tried them but I looked into it. The consensus I got from the guys who have ordered them is that the first few months are cool because you look forward to seeing what you get but in the end it's stuff you really don't use and you end up using/buying your go-to tackle.
Give it a try for a few months and if you don't like it just cancel.
Or the other option is go on YouTube and watch the vids of the guys opening their boxes every month, cherry pick and just buy what you'd like to use from that box. Might be cheaper than getting the whole box.
Or get the subscription, keep what you want, let a few months of unwanted items pile up then sell them as a lot.
