This is a great little dryer overall! It’s fairly quiet, lightweight, and works well for smaller loads—it dries them quickly and efficiently. It can fit a set of queen sheets, but those take about two hours to dry, and you’ll need to pause and rearrange them partway through for best results.

This is a wonderful little machine! It fits tiny places, is easy to move around, and does a good job of drying the clothes. I mainly wanted it for sheets, towels, & lightweight blankets. I washed my 2 tablecloths and 4 chair covers tonight. Within a couple of hours, they were back in place clean and free of cat hair. I dried the load in two batches, first the tablecloths and then the 4 chair covers. Both dried very quickly.

We purchased this compact dryer for our 2008 Leopard 40 catamaran, and it has been a fantastic addition. We’re in the Caribbean where the wind can be very strong, and we noticed our sheets were starting to fray from flapping so hard while air-drying. This dryer solved that problem perfectly.

Works well for lightweight items. Heavy items like jeans towels, flannel don't come out as fluffy. They have more wrinkles than in a normal dryer and take a lot longer. Works well for small loads other than that. It fits in our 5th wheel rv trailer compartment and we just leave the door up with the vent hose pointed to the outside. Our trailer came with small washer but no dryer.

I definitely recommend this product. It works so well! The only think I would have liked it if it came with a few extra lint filters. They do need to be replaced eventually!

It’s just my teen and I in a small house so this sized dryer works well for us. Space is a valuable commodity around here so this was a great find. I also use a portable washing machine that pairs well with this dryer. This dryer offers some flexibility in that it can be wall mounted (mounting parts included), placed on a solid floor or set on a shelf. To maintain safe airflow you’ll want to avoid enclosed cabinets however. I’m planning on getting a small rolling dolly to put it on but for now it’s just on our tile flooring.

I just received mine yesterday, ran the cycle perfectly fine to clean it out for the first time. Made my first cup of coffee heaven this morning! This was a pure party in my mouth experience! I had to google a few things for use but definitely worth the purchase!

Fantastic!! Love everything about it! The frother is so much fun, it’s not just for the coffee I use it for hot chocolate and it’s so yummy. Easy breezy to use. For the price you can’t beat it but be sure and get the frother too!

I love my Nespresso! I have had it for a few months now, and have had no issues. I am one of those girls that usually gets an iced coffee on her way to work every morning and this has broken that habit! I Have saved so much money since buying this machine.

Great TV for viewing and even gaming. Great picture. Perfect for a spare room or kids room. Sounds decent. Roku isn't my favorite operating system but it gets the job done with ease. The remote is a regular Roku remote which is just fine it works a little slow but it works.

TV works great and picture is good. It is in my guest room, so I do not watch on it very often. Easy set up also. Very happy with it.

Very nice inexpensive smart tv. The sound quality is not great, but better than some. We are able to use it without a sound bar so that is a plus.
