I can't answer your question about the microsilk personally, but I know my dealer loves it and recommends it all the time! Your wife may want to look young, but I think feeling young is even more important! That's how I would try to sell her on a hot tub! Soaking in hot water is the best way to relax, loosen muscles and enjoy the outdoors when you normally might be inside looking out at snow and ice! It provides therapy to let your body feel healthy. I had Lyme disease for years and I had to convince my husband that the hot tub was a last resort therapy because nothing else was helping! My family joined us for a test soak at our local dealer and we all fell in love with soaking in hot water! I will always credit my hot tub with helping me manage and finally beat Lyme disease! In that respect, I probably became at least 10 years younger! Lol!
We have a Marquis Epic purchased in 2005 and if I needed to buy again, I would go with Marquis
the therapy jets on my tub are amazing! Good luck and seriously you're only as old as you feel!
