I read somewhere that the garlic mincer didn't work as well as described - maybe it was that it was hard to get all the little pieces out, or hard to clean? Can't remember.
This is my favorite garlic tool - it makes very very thin slices, that you can leave as is or easily zip a knife over to mince.

Regarding the peeler, if you want that kind of thing just use one of those usually-free rubbery jar-openers that are often handed out with advertising on them. I have at least a half dozen advertising various banks etc. If you want to buy one, go to the dollar store. However, I've never had an issue with peeling garlic - just slice off the root end, make one vertical slice through the skin, or cut the whole clove in half lengthwise, and the peel will slip off. Or, if you're going to be cutting the clove up anyway, lay the unpeeled clove on the cutting board, place the flat side of a heavy knife on top of it, and give the knife a good whack with your fist. You can pick the peel right off of the smashed garlic, and if you then want to mince it, it only takes a few passes of the knife. (Yeah, this all sounds like more trouble than the mincer you linked, but consider whether the mincer seems like a nuisance to clean and to get out all the little garlic pieces.)
I like my OXO GoodGrips garlic press

Mine is the older version with softer "flaps" or "baffles" where the thumb goes.....but it broke after 30 years. The little red plastic part flips around to push any remaining garlic backwards through the holes, for re-pressing or cleaning. But honestly, even before mine broke I usually used the slicer.
I use the plastic organizer boxes in my refrigerator too - shoe size and the one that's almost double a shoe box. For the freezer I use similar inexpensive organizers, but plastic baskets (with holes); I suspect that's better for air circulation.
