I bought one of those $20 titanium baskets.

It was delivered late today. Pulled two shots and both were slightly over extracted compared to the capfei I've been using. (The last basket photo) It's incredibly light, it feels like you should be able to crumple it in your hand but that's obviously not possible. Doesn't appear to flex at all during shots. My shot seemed to be a bit brighter with this basket, I'm guessing something related to my holding more heat in the puck initially.
