This 4x1 4K HDMI Switcher with Auto-Switching and Audio De-Embedding from Key Digital is a high-performance, four-input HDMI switcher that supports up to DCI 4K30 12-bit 4:4:4 video or up to DCI 4K60 8-bit video. It also accepts SD and HD video over HDMI as well as VESA resolutions such as VGA, SVGA, XGA, WXGA, SXGA, and UXGA while supporting a maximum data transfer rate of 18 Gb/s.

The KD-S4X1X-3 features front-panel control, CEC-passthrough as well as IR control using the included IR remote control unit.

The full buffer system manages TMDS reclocking/signal regeneration, HDCP authentication to source and display, and EDID control handshake.

Easy to use for older folks - and FUN.....???
Size: 100ft, Color: Black
Love the light weight. I can turn the spigot just a bit and the hose will grow in length as i walk around to the front of my house. It's just enough to get a good drenching without knocking my plants around. However, the nylon covering snags easily, and I can see that I may need to replace the hose quicker than I had hoped. I'll probably get the same brand of i have to do so. The sprayer is decent quality, and its multi-functions are handy. I kind of like watching it shrink as I empty it and wrap it up. Never thought a garden hose would actually add a little fun to the chore!

Nice, light hose with nozzle
Size: 25ft, Color: Black
Nice short expandable hose. I had a longer expandable one which got a big leak. So I bought this shorter one since I only use it to water the plants on the patio. So far, it works great; but people have to know that short means short. The nozzle fits this hose; my other nozzle is too big. So having the short hose and the right nozzle in one package works for me.

Love this light weight flexi hose!
Size: 50ft, Color: Black
Great hose. This is my third because the only downside is that the area connected to the spigot can crimp and ultimately leak. It’s easy to keep that from happening if you are the only one using the hose. But if others, like your kids or a garden helper use the hose, they don’t always recognize that.

Weak but excellent please read.
Size: 50ft, Color: Black
Breaks a lot, but Is 100% convenient. My third annual purchase. Beats rubbing stuff off of twisted rubber hoses. Darned if u do. Darned if u don't. A 5-10 yr version one of these will outsell the entire market.
