I got a fossil zipper wallet at tj maxx about 6 years back as well and it looks and functions just like it did when I bought it! It’s been tossed around in various bags with lots of other stuff, keys, etc. never let me down yet. Daily use.

I’m not sure of the specific part you’re referring to (solely my ignorance on part names) but I’ve been using a kitchenaid two-speed for years and it’s been great. I use it several times a week and it’s been through frozen food to sauces with no issues. I have the older model, google’s telling me it’s the khb1231
