Universal grease tray with catch pan for 3/4/5 burner gas grills vs Matchwaves 100 pack grease cup liners for Blackstone griddles

Key Differences

Matchwaves (A) is a pack of recyclable heavy‑duty aluminum grease cup liners designed specifically for Blackstone griddles and is noted for keeping grease contained and being disposable; Uniflasy (B) is an adjustable-length universal grease tray built for multiple grill brands with a leak-proof channel but has mixed durability reports (including rust) and some foil inserts that may be too small. Choose Matchwaves if you want a heavy‑duty, disposable liner solution for Blackstone models; choose Uniflasy if you need an adjustable, reusable tray that fits many grill brands
