I bought this at my local grocery store when it was on sale and I had a coupon. I thought it was a great concept that I did not have to worry about forgetting to put in the dishwasher detergent. I could literally load the dishwasher and press start. My dishes always came out clean and never had any water spots. The dispenser was small enough that it did not get into the way of the dishes. I think this product was great and worked really well, but it is more of a convenience product, not a necessity. It is more expensive than normal dish washing liquid, but you pay for the convenience. I really only gave this a try because it was on sale and I had a coupon making the price very reasonable. I do not know if I would spend the extra money on it again, but it does work well. I actually had to remind myself to look and see when to refill. It lasted longer than the 12 washes for me, but we do not overload the dishwasher and tend to have smaller loads.
