I cant comment on the waxes but i do own a meguiars microfibre mitt and drying towel, the mitt does a good job on cleaning and feels soft on the car but the fit is far from brilliant, i havent got small hands but its really lose which is irritating, but saying that id probably buy it again.
The drying towel is below the standard that ive come to expect of meguiars it's unable to dry a whole car, there are much better drying towls out there such as the miracle dryer
Autoperfection
I also heard on the meguiars forum that that meguiars are unable to find a bucket in the uk that fits their gritguard, so you have to buy the meguiars bucket aswell
Hope this helps
