You can't go wrong with anything Dye. I play a lot and if you follow the manual and just keep it clean and fresh batteries installed this Hopper will not let you down. I have used it on 5 different PB Markers and the R2 Rocked them all. No ball breaks or slow feed problems. I shot my M2 on "uncapped semi and the R2 was flawless. Bottom line... "Get one or get out of the way!!".
