Harvest Right Home Pro Freeze Dryer
Close to perfect .

This is a cool little machine. The only reason it doesn’t have a solid five stars is there was a small vacuum problem when I first received the unit. I was pretty sure it was just a door adjustment that was needed. So, I called Customer service. Which by the way went exceedingly well. They sent me a video confirming my suspicions. The problem is corrected. I’ve ran four batches and they’ve all turned out as I expected them to. If I was gonna do anything, I would’ve purchased a larger model. As it’s hard to get ahead on your food storage when you’re eating it all. I am now going to try the candy mode. 😃. My overall experience from ordering, to customer service, shipping (which I would give the person that delivered it a 10.), delivery, and set up was great! I would recommend your company to anyone wishing to buy a freeze dryer.

Thank you for a wonderful experience.

Great company

It was time after5 years to replace my pump. The pump arrived on time and worked great. If there is any criticism I have. They should state their shipping method on their web site. Not all people can use FedEx. Other than that I was super satisfied with the product and seller

EcoFlow RIVER 2 + 1*110W Solar Panel
EcoFlow

Well.... let me tell y'all, this Ecoflow River 2 is somethin else. It's small and portable AND the right size to throw in the back of the truck for our weekend camping trips. I've been using it to keep teh lights going, charging up the small electronics, and run the fan in the burning hot nights. WOO the solar panel was easy to set up and work like a charm....even when the sun doesn't want to come out to play hahaha. Great reliable power if I say so myself

Bluetti AC60P Portable Power Station Solar Generator
Bluetti

Happy with the Bluetti AC20P purchase. It's lightweight and easy to carry, making it perfect for outdoor adventures. I love that it's water-resistant and dust-proof, so I don't have to worry about where I take it. We've taken it to Death Valley through the desert and then near Rae Lake. Love the portability

Harvest Right Home Pro Freeze Dryer
Freeze Dryer

Got a large freeze dryer just so we can make and preserve as many food as possible! I am very pleased with the quality of the freeze dried food and variety of food that we can put into the system. The only negative was that we had to wait about 4 weeks for the Freeze Dryer to arrive at our place. I would have given this 5/5 if it wasn't for this problem. I guess this product is very high in demand
