I must admit, I was a little nervous about using the company initially. I was looking for a K1 Max, It was a lot cheaper with 123-3D than every where else - too cheap!. So I thought I'd take the risk, I am so glad I did! It turned up pretty much the next day. Everything well packed I had the printer up and running within the hour and it worked seemlessly. I've now put a good few hours in to printing and it's still as simple as day 1, just click and go. I have not had to change any settings. Perfect for someone getting back in to 3D printing after failed attempts and inferior printers from years ago. I will certainly be coming back for supplies. Ps Thanks for the free pens and marker :-)
