I believe someone did recommend the set I bought, but I can't really fault them, as they didn't have my lens sitting in front of them. I bought them for a Tamron, 28-200mm 1:3.8-5.6 lens, which he guessed had a 62 mm thread. I didn't know any better how to check it on the actual lens itself, so I checked online, and it seemed to say that my lens was a 62mm thread. It isn't, but the lesson was well learned! I definitely won't make that mistake in the future, at least. I doubt it would be worth returning, as the kit was only worth $15 dollars, and as someone else pointed out, I may end up with a 62mm threaded lens down the road. I'll just hold on to them. It'll be a healthy reminder to not be so hasty!
