Digital amplifier power has never been more compact and affordable: With a size of just 190 x 35 x 102 mm, the three new ESX QUANTUM QM miniature power plants are convincing all along the line. The QM amps offer state-of-the-art technology in a very small space and are all solidly constructed. All three amps are based on the somewhat larger sibling models of the ESX QUANTUM QL series, only a bit more compact and much easier to install. Thanks to the high level inputs including EPS and the automatic turn-on function, they are also perfectly suited for integration in factory sound systems. Each model is also equipped with a compact bass level remote control.

Good Dog Toy
Color: 3 PCS
These have lasted my dogs way longer than I thought. My dogs chew on them probably a few times a week, they rotate which ones they use. The only reason I am not giving 5 stars is because they are small. I think Large Chew toy, I think a Large Chew Toy. These are better fitted for Medium to Small Sized Dogs.

Durable for the aggressive chewer.
Color: 3 PCS
My dogs love this product. One of them is a really aggressive chewer. She will chew on this for over an hour at a time. They are very durable and I don't have to worry about them breaking off large chunks and swallowing them.
