They are mostly nice. I honestly dont feel the Viper is good value for money. The Muk Luks were so flat inside and had zero arch support, which in turn caused my knees to roll inward and my feet pronated. Arrived a day early! I have absolutely zero complaints. I was a little hesitant because some of the reviews mentioned that they weren?t sturdy enough to slide in and out from under the bed, but that hasn?t been a problem at all. This was the perfect addition to our closet area. In the end, we?re pleased with the finished results and it?s a sturdy unit that will be quite durable. I like the different sized sturdy compartments for different spices, but it is a bit awkward when you try to sprinkle one spice and the whole holder is being shook around since you cannot take the individual jars out of the holder. The silicone bands are surprisingly good at keeping the phone from falling out and down but the mount does not hold its place well.
