This is the newest top-of-the-line 100% stainless steel iSi "Cream Profi" Model 173001 whip cream dispenser. Stainless steel body, stainless steel head and metal charger holder, this is (in our opionion) the best 1 quart (1 liter) iSi produces. Includes a full 2 year warranty from iSi. The 1 quart Profi Whip is the same model used by most Starbucks(TM) world wide. We strongly recommend this whipped cream dispenser.
