I have two of them I bought from Advance Auto, and I love them. I don't know if they are truely MF though. Mine look like that, but said Chenelle on the packaging, yet on the product list listed the typical 70/30 mix of the two fibers contained in MF. I really like it a lot, was actually going to post a review of them in a few days after I got good pics. I use them in an Accumulator-style wash with the nozzle inside the mit spraying soapy water. The mit holds a TON of water and soap, and is absolutely the thickest mit I've ever seen/used. I absolutely love them. Only downside is that they take awhile to dry (couple days, even in 85 degree + heat). I honestly can't say enough good things about them. My only concern is that maybe down the road they will start to really hold dirt, but at Advance Auto here, they were only $5 US a piece. For five bucks, I dont think you can do any better.
