I've been 3D printing for about 3 years and have used an Anycubic Kobra Max...whcih I thought was a great printer but it has issues (like I had to replace the printhead 3 times, failed adhesion, etc.) so I thought it was time to look for a replacement. I spent several months doing research, reading reviews, etc. I decided to go with a Prusa MK4S. I got it yesterday and the set up was a 9.7 out of 10. The instructions for attaching the spool arm could have been better but all in all, it was truly out of box, plug in, and print (after an easy selftest) but that is not the point of this review...this is: I ran the first suggested print and it was VERY easy. Some points I want to note: 1) The menu is quite easy to follow 2) The ease of installing filament was drop dead simple 3) The fact the print head set up the filament AND cleaned off the test run was stunning 4) The 'self check' during print set up was a tad noisy but tolerable 5) The printing was very smooth and quick All sounds good so far but wait... Ok, the 'test' print went well but let's try a tough one. I choose a complex print of a nice 'pencil' cup with dragons all over it. (The Anycubic required supports). What amazed me was the cup print seems to NOT ask for supports even though there were overhangs. Ok...let see how this goes... The cup took 12 hrs and WOW! Talk about amazing difference! The Anycubic did well but you could tell it was a 3D print...nice but 8 out of 10 for smoothness/etc. This one (MK4S) was stunning! It needed ZERO supports and the print was so smooth I had to run my hand over it to recheck...nope! No lumps, bumps, ridges! This is an amazing printer! So sturdy, so easy to set up, and SO much better in print quality. Downside? $500 vs $1,200. It is an expensive printer but the quality shows! Can I recommend the MK4S? Absolutely! If you can afford it then by all means get this printer!

Broke in a month. Support is a joke. Repair wants you to professionally pack it better than it came and is extremely picky. Device is finicky. Purchased assembled unit to avoid issues and had nothing but issues with it. Would look elsewhere if you want wanting a trouble-free experience.

THE BEST PRINTER EVER! Prints SO fast, worth every penny. Only real thing is the flexing, which ink if it's the printer or operator, but whenever it cools in the middle of a print, everything warps. I printed something to fit against a flat wall, and sticks out on each side from the wall like half an inch. I think it's my fault, so 5 star

Bought the unassembled version and it arrived with damaged components. Took too long assembling and was outside return window. Romario at Prusa Customer Service worked with me to diagnose the problem and ship me a new board.
