Best bang for your buck period. I dropped mine in the mud and just rinsed it off and it sounded good as new, very tough little call.

Honestly these are a steal for a 10 pack. The action feels pretty snappy and they haven't failed me yet on my hobby projects.

Not as good as some of the other double features out there like the old Elvira sets, but still decent. The sound quality on Petticoat Planet is a bit muffled in parts and the acting is... well, it's a B-movie. It's fine if you just want some background noise or a laugh with a beer.

As a professional artist, I was skeptical about these "gel" plates compared to traditional press work, but I'm pleasantly surprised. The 5x7 is a great portable size for demos. It picks up incredibly fine detail from organic materials like leaves. Pros: durable, easy cleanup with just baby wipes, and consistent results. Cons: the plastic packaging it comes in is a bit flimsy for long-term storage, so you might want to keep the clamshell it ships in.

These are way better than the generic stuff you find at the big box stores. The grit range is perfect for getting that mirror shine on metal. I used them wet and they held up really well without tearing immediately.

I was skeptical about the black tape thing but they're surprisingly comfortable. Used them before a wedding and my skin looked way smoother. Kinda weird to wear but worth it for the results tbh.
