There are many reviews on these two boot dryers so I will make it short.  The Peet Original Dryer and the Maxx Dry XL are both excellent products.  The Peet is absolutely silent, extremely efficient, rock solid stable and inexpensive.  The plastic is good quality and the dryer is made in the USA.  The boot points up at a greater angle than the Maxx Dry which really dries out the toe box.  I think that my boots are dryer with the Peet unit, but they are on the unit for about nine hours verses three hours on the Maxx Dry.  The Maxx Dry is made in China and the plastic is heavier than the plastic Peet uses.  The fan does make some noise, almost like a bathroom exhaust fan.  I like the fact that the Maxx Dry also dries gloves at the same time or a second pair of shoes.  In my experience, the Maxx Dry is not quite as stable as the Peet Dryer and is more likely to tip over.  I am in my work boots for fourteen to sixteen hours some days and nothing is better than dry boots the next morning.  I use both dryers every day and would not be without them.  As an added bonus, I can now keep my teenagers $100.00 running shoes from smelling and ending up in the trash before they are worn out.  These dryers are very useful products in the home and very few people know about them.  The first dryer that I bought years ago on sale lasted only about a month so I was surprised by the 25 year warranty on the Peet Dryer.  I recommend both units, as each one has its advantages and both are well worth the purchase price.
