The M37 line is quickly becoming a newer fav of mine. The prices are reasonable and I am pleased with the results. Quickly these products are becoming my go to:

1. N-914 excellent results with a waterless wash presoak and rinseless wash. my go to setup now for my Daily every 1 - 2 weeks
2. Hydro blue. on wheels and paint works well and is quick and easy
3. The interior line up is fantastic. I have had great results
4. Leather Shampoo followed by UV50 made my seats like new and added a silky luxury feel

Can't wait to get this and use it with hydro blue.

The only one negative I have is that the 1 gallon bottles sometimes split open on the upper side but AG has always taken care of any issues I have had
