Shaker cups

Who makes the best shaker cups for mixin protein powder. The ones at gnc never last very long. The o ring always wears out and they leak.

The kind with the metal whisk ball are by FAR the best..I think they are called "The Blender"...best shaker hands down. Works as good as an electric blender...
Its a shame the way GNC rips off the public...I confess to occasionally buying stuff there, its usually about double the cost of stuff you can get online..basteerds

iagreee with dzone...the ones with the wire wisk balls

I JUST USE A BLENDER

the wire wisk ball ones i have one from gnc that i have had for a couple years now with no problems

Thanks I'll have to pick some up. I have to use them at work while I'm on the go.

i'll have to pick one up to mix my protien powder, water and dry oates....yummy

THEY ARE ALL OVER EBAY FOR C H E A P !!! THE WIRE WISK ONES EVEN COME WITH A FREE T-SHIRT

CHECK EBAY

I just buy them from walmart for like a buck. They don't have a ball or the thing at the top, but they work for me and are much cheaper

You can get them at Whole Foods or Vitamin Cottage for about 5 bucks or so. No chunks at all with that wire wisk ball. Its called Blender Bottle

I just use a KitchenAid blender..I dont take shakes anywhere, just the AMPED and you dont need a shaker for that.
