A few months back I purchased a new Ender3v2 from Comgrow on Amazon. When my hot end fan started making noise (common issue with these fans) I contacted Comgrow and with one email they had a replacement at my door in three days. Thats what I call customer service. I became addicted to 3D printing and had to have a larger machine. I settled on the CR-10 V3. I went directly to Comgrow and found that the refurbished V3 was half the price of a new one. I read Comgrow's refurbishment guidelines that printers were no more then 30 days old since originally purchased and refurbished top to bottom by their team. Buying 3D printers new can be scary but refurbished? I decided because of the warranty to take a shot and order the CR-10 V3 and a CR-10 Mini both refurbished to put them to the test. First up was the V3 as it was most likely to have a problem. I unboxed it and could clearly see it was never run. I found the issue to be a plugged 1/2 inch piece of Bowden tube someone decided to use as a filament guide. I removed the piece and replaced it with a longer piece of Capricorn tubing and the printer works flawlessly. Next up was the CR-10 Mini and it was brand new, it must have been a direct return as nothing was ever taken out of the box. So in summary I purchased two perfect printers for the price of one new one. Don't take my word for it though, I did complete unboxing and build videos that you can go and see for yourself on my YouTube page, Upgrades Complete. I'll be ordering a few more every month but only from Comgrow, because I trust them. It's rare today to find a company that stands behind their work like this.

Almost afraid to review. It may be too difficult to purchase another if the word gets out.

I would rather spend less on a machine I already know from a company that went to great lengths to QA the box before it was sent to me. Its a great service.

I received the printer with a broken turbo fan. The yellow wire that is soldered to the board was off. It was missing the cover on the daughter board. The brown lead to the bed sensor had a short in it which created an interesting scenario for a first timer where the gantry dive bombed into the bed. Other than those issues I’ve spent about 20 dollars and 8 hours of my time to troubleshoot and fix it.

My new Comgrow Referb Ender 3 Pro works perfectly. I have been printing from a few minute after the easy assembly. I have printed everyday since then with no problem. I would recommend these printers to anyone that is interested in a great printer and saving some money to buy filament.
