Rating: - Excellent customer service!
The Blitz folks mis-addressed the package containing my jewelry cleaner, and so it got delivered to the wrong address and was destroyed by the dogs in the yard. My email complaint to the Blitz customer service was answered almost immediately, and a new bottle shipped out free of charge. I just received the second shipment, used the cleaner, and it's great!!! Highly recommend doing business with Blitz!
Rating: - excellent but don't use as much as they say
This is an excellent cleaner but you don't need as much as they suggest using in the ultrasonic cleaner. A capfull or so is fine if all you're doing is a few items. They suggest a lot more than that and when I did that the jewelry was very soapy afterward no matter how much I rinsed.
