The newly developed ESX QUANTUM QE series is a class of its own. Conventional high power digital amplifiers usually cause interferences in the vehicle and disturb the radio reception. Not so with the new QE models: During the development period, special attention was paid to achieve an emission-free music playback. Also the sound is perfect,  because high-quality components guarantee an audiophile sound experience at its best. The features are also impressive: Auto Turn-On Function, EPS, variable crossover filters – everything your heart desires is on board. High-quality connectors and screwed RCA sockets complete the perfect appearance. All amplifiers are delivered with a sophisticated level remote control, which can be installed very space-saving with or without housing.

Great product to keep moisture in
Size: M (up to size 9)-Beige
These are so cool. I was skeptical at first. After an at home pedicure I put lotion on and keep these on for about a few hours. The moisture retention, and comfort and fit or absolutely amazing!

These work!
Size: M (up to size 9)-Beige
I’ve had dry cracked feet my whole life. Tried these last night with lotion from Trader Joe’s and literally overnight my feet are the softest they’ve ever been. I put a pair of socks over them and went to sleep with them on. Hard to walk around with all that slippery-ness but worth it! 10/10✨👌
