Bests & Worsts Reviews from Amazon

I'll start by saying I'm a mechanical engineer and consider myself reasonably good with these kinds of products. I still opted for a printer that's ready to go out of the box for conveniences sake. I'm only going to list a few of the issues I had with this printer over the three months before it became unusable and I returned it, only to have customer service send it back to me even further damaged from the post. It came with outdated software and needed a firmware update. I had multiple filament blocks. I had to pull every part of the extruder apart and even had to drill out the nozzle once the block was so bad. So make sure you have plenty of tools if you do decide to buy this printer. A leak above the extruder was really frustrating. It took me four attempts of pulling the assembly apart to repair. It would start slow and drip not burnt filament on to my prints. Ieventually had to sand down the top of the extruder. I don't believe it was ever flat. I'm just going to skip past the others and get right to this issue that eventually had me returning the printer. About 70% before I updated the firmware, and about 40% of the time afterwards, prints would stop mid print. Or fail to start all together. I battled hard with this issue and tried everything customer service recommended and I could find online. Including trying several different versions of slicing software. Customer service eventually agreed there was something wrong with the card. After I lost a lot of money in wasted print filament. So I sent the printer in for repairs. I thought I did a great job of packaging it, but apparently the arm got bent in transit and this has voided the warranty! So now they're sending, what really is a pile of junk, back to me without even giving me the solution to this problem I spent many late nights trying to solve myself. I feel I could fix a bent arm, but they won't help on their side! I now truly regret this purchase. It's been a huge waste of time and money.
