Athletic Works 24oz Aqua Protein Drink Shaker Bottle W/Mixing Ball

I like the size %26 that it's easy to close, etc., BUT mine has NO SILICONE GASKET / O-RING, OR, THE LID %26 BOTTLE JUST DON'T MATCH UP RIGHT. I had previously tested it WITH JUST WATER, %26 it DIDN'T SEEM to leak, but water may have landed elsewhere, just not on or in front of me. Yesterday, I tried mixing a med in it that I SPECIFICALLY BOUGHT THE SHAKER BOTTLE FOR (I left out the mixing ball, just to be safe), but the shaker bottle LEAKED ALL OVER, %26 YES, THE TOP WAS SCREWED ON CORRECTLY %26 THE CAP WAS CLOSED CORRECTLY, ALSO. SO, I ended up with my expensive med splattered in the kitchen %26 all over my clothes %26 the food, so I actually couldn't serve that food to others. Not a happy camper %26 I hope my clothes aren't ruined. This bottle was in a delivery order, but next time I'm at the store, I'll check the other bottles of this brand %26 model to see if they have silicone gaskets / O-rings in the lids. OTHER THAN THAT ISSUE, I'm ok with using this to drink my med if I've already dissolved my med in something else (has to be shaken, not jst stirred) %26 the bottle is sturdy, etc.

I purchased two of these bottles. One in the mint green color and the other in black. The black one doesn't leak at all and works perfectly. The mint green one leaks bad. If I use the mint green one I can't really shake it without being over the sink so it's basically useless. Not sure why the green one leaks but the black one doesn't.
