4-in-1 Bucket Tool

I must love buckets — they’re all over my home, shop, and garden — but the ones missing their handles cut into my hand when fully loaded, and the new ones can be a pain to open. Fortunately Prazi makes the 4-in-1 Bucket tool; it can serve as a replacement handle, and it’ll also help you pry off those stubborn lids.
Even if your bucket still has its handle, the 4-in-1 Bucket Tool will fit over the standard five-gallon bucket handle to give you a wider grip. It’ll open the larger buckets with plastic lids or metal tab lids, and it’ll pry up a regular one-gallon paint can lid or one of those pesky pour spouts.
The 4-in-1 Bucket Tool sells for about $7.

Anybody ever use one of these? When we are changing air scrubber media, we will open 700 five gallon buckets in a day. Are these better for prying lids of than my channel locks?
I find that one of these works fairly well on 5 gal paint pails:
