I picked one up at the Autopia Clinic back in January and finally had a chance to use it a week ago. First off, it is a bit thicker than a standard Sonus DAS orange pad, and feels just a bit stiffer as well. I could load it with a bit more product than usual and not get a bunch of slinging. I used Meg's #80 on part of the hood of my Miata, and then some SystemOne polish on the trunk. I found I could carry a lot of product and work it for a good long time. I felt it gave me really good results, especially with the SystemOne Polish which I used for the first time. I used it on a PC 7424 at speed 5 with a 5" backing plate.
(NOTE: I should tell you that my niece's fiance is the son of the folks who own SystemOne and he gave me a few bottles of this stuff to try out. I was impressed, but I'm also not anywhere near the detailer of guys like ScottsWax or Accumulator or others here. All I can say it worked very well for me and my admitedly limited abilities. Although that might actually be saying a lot! Anyway, I thought I should be up front about this product.)
Back to the Sonus Swirl Buster pad. Overall I do think it offers an extra edge over a more conventional pad and I was very pleased with the results. If I can get rid of swirls with it, and quite quickly at that, then anyone should be able to.
Here's the part I hate to tell you about though: when I went to wash it I used my usual method of soaking in a bucket of warm soapy water, then squeezing out the product collected in it. I didn't let it soak for more than 5 minutes and while working the product out I noticed the velco backer was just falling off. My other Sonus DAS pads have actually gone through the washing machine a couple of times without the slightest hint of failure. Like I said, this just soaked in a bucket of warm water for no more than 5 minutes before the velcro started peeling away and more than half of the surface came loose. I immediately contacted David B, who asked that I contact Customer Care, and Lynn responded very quickly and had a new one sent to me next day. If this is the level of customer service I can expect from Autopia in the future, they've got a customer for life. Things can always go wrong, but how the supplier/vendor/manufacturer responds to problems is the real measure of quality in my book. DavidB and Co are just top notch.
I think those of you with far greater experience than I have, with a more discerning eye than I have, will find this pad to everything it claims to be.
