If you have researched this and understand the problems with the bed, fan wiring and grounding, you are willing to spend a whole day setting it up and have the ability to make a parts to blow air and stop fires then go for it. Otherwise don't buy this, it's not for you.Power supply, it's marked as 110v on the site but the can be switched, mine was already set to 230v when it came. I would recommend removing the supply to check before you plug it in. Look for the little red switch and make sure it is right for your country.Power cable, the mains cable looks like a euro fitting so this needed changing. The fan and pump were euro too but these plug into the back of the machine so don't need changing.Mirrors, these were completely out of line, I ended up stripping the parts off the machine, cleaning up the edges, switching the screws for better quality M3 hardware, then realigned everything. You need patience for this step, all in it took about 4 hours.This laser needs a fan over the work, these are easily 3d printed, I chose a 3d printer blower fan, having the compressor going was a pain. Wired to a separate 12v supply with a power switch drilled into the control panel.The bed, this is terrible, remove the middle spring section and replace it with some sort of mesh. I used the mesh from an unused small disposable barbecue.My summary - this is great, really really great. But be aware you are buying a device that needs attention. I hooked up the power about 6 hours after opening the box. I removed all the blue film on the metal parts and checked every connection, some were loose, 1 wasn't connected.Look at the different software too, k40 whisperer is extremely good.
