Love the product....it deserves a 5 star rating. The company falls short in customer service. Products are only warrented for 30 day's and this includes defects in workmanship. Bought a frost buddy. Then down the road they came out wit a lid and straw top. Bought that too. But every time the knew lid is on it leaks. I've tried other fb lids and they leak as well. Wrote to customer service and they don't want to own the proble and replace the unit for one that won't leak when drinking from it because it's more then 30days since purchase. Not a good way to service your customers Frost Buddy's and Brock....cause you just "FROSTED" this customer!!! The quality of this product should be for lifetime on workmanship to perform as stated. I have invested in three frost buddies, one XL shaker version and many add on accessories for them....this should not be the review I'm giving or what I should have to tell others that's my experience with Frost Buddy.
