Kramer VM-3UHD | 1x3 4K UHD HDMI Distribution Amplifier

I ordered this unit but initially there was an inventory discrepancy and the VM-3UHD was out of stockhowever Matt from Viixim Inc (seller) asked about sending me an upgrade model Kramer P/N: VM-3H2.VM-3H2 is upgraded model that supports a wider bandwidth going up to 18GBPS and He told meit is in the larger MegaTool case size. I received item pretty quickly. I really appriciate their great customer servicenow let 's talk about Kramer HDMI Distribution AmplifierI have used more than 6 different HDMI spliters or distribution boxes from different brandsome of cheap one (less than $100) work initially but they didn't last couple months.most of them died with electrical issue or just toally dead after 3-4 time of use,My goal is sending video presentation from one of PCs to 3 device (projector, PC monitor, black magic design ATEM).I have used only 3 weeks so far so I can't really tell about Kramer HDMI Distribution Amplifier. it is working ok but I see that it is little sensitive about either Amperage or voltage. when I connect it to the UPS, projector is not getting signal but if I switch to wall outlet directly it is working. I may have to measure Amp/Volt difference between input from wall outlet and UPS outlet. maybe it is not designed to distribute to three different type of device. I am going to update my review after couple months later
