The approximately palm-sized 2-channel mini power amplifier QUANTUM QM-TWO caused amazement right after the presentation among ESX fans and connoisseurs of the car hifi scene. The small powerhouse with a whopping 240 watts RMS output was immediately traded as an insider tip. After last year's improved V2 version with incredible 300 W RMS performance topped that again, ESX is now adding two more models in the QUANTUM QM class: The powerful QM-FOUR power amplifier is now available for 4-channel applications, who want to drive a separate subwoofer, can now use the new Monoblock QM-ONE. Both power bars deliver a whopping 360 watts RMS and are visually perfectly matched. Modern and efficient Class D technology is used in all models, combined with EPS, top features and perfect sound characteristics. The QM-ONE Monoblock is not only visually the perfect play partner to match the QM-FOUR. If a separate woofer is also to be fired, its area of application is clearly defined. With a full 360 watts RMS at 2 Ω, sufficient steam is provided, and the bass level can even be conveniently adjusted using the remote control.

The QM-FOUR-PP Plug&Play Edition is ideal for reinforcing a factory system. Only one condition has to be met for this: The radio must be equipped with a modern Quadlock plug ex works. In this, the loudspeaker plug insert can be easily removed and connected to the enclosed 5 meter cable harness of the QM-FOUR-PP. Finally, the QM amplifier only needs to be supplied with power and that's it!

Works & Looks Great!
This item comes with two options for sticking to the sink, suction cups & an adhesive thing. I decided to try the suction cups first, that way I can remove them to clean, plus I wanted to test out the position of where I put it on the sink. They work great! I haven’t had to re-stick not once. Great staying power! And it looks really good! Also, the seller sent a follow-up message just to check in & offer answers if any questions arose. That meant the world to me, like it’s not every day a seller cares what you think once money changes hands. 10/10 would recommend!

need a smooth sink surface for this to work
Color: Silver
Suction cups didn't stick to my sink and kept falling; to be fair, surface of my sink is textured.

Three months later, it's a keeper
Color: Silver
I hate it when reviews are left one day after the product arrives. At that point, there's no way of knowing if the item is going to last. When my last sink caddy went bad (the suction cups rotted out and the wires had started to rust), I ordered this as a replacement. Inexpensive, functional, worth a try. There were two things that impressed me when this arrived. The suction cups weren't permanently mounted, so if they fell apart, the caddy was still worthwhile. Secondly, the company offered free replacement suction cups if the time came I needed them. That struck me as above-and-beyond; I had no idea this was part of the package. I'm happy with this. It looks good, I detach the sink caddy regularly when I want to move it out of the way, and it pops right back into place. For the money, I don't think you can beat it.

Beautiful Shelves.
Color: Brown, Size: 3Tier48in, Color: Brown, Size: 3Tier48in
Did not come with instructions but easy to assemble once you start putting together. Very sturdy and well made, real wood shelves, not too heavy but can definitely hold a decent amount of weight. The shelves themselves are rough (could have been sanded better) but where it’s for decor and not every day use, no one would ever know. I love it.
