Good way to get into larger prints, nice upgrade from my small Tina2s. Still learning and dialing in settings, but decent print quality so far. Easy to put together, most parts preassembled. Comes with printed instructions but still more helpful to follow Longer's YouTube video. Despite the large size printer is solid and sturdy, doesn't flex while printing. Like the touch screen, easier to use than the buttons on my previous printer. Not quite as responsive as the screen on my phone but works well for the simple functions of the printer. Simple straight forward UI is nice for beginners. Good fine-tuning functionality. Main downside is there's no automatic leveling; it took some time to dial it in manually. Luckily shouldn't have to do it too often

The media could not be loaded. i recently got the Longer LK5 Pro 3D printer, and I’m absolutely loving it! This printer is so easy to use, and the print quality is amazing with great attention to detail. The printing speed is super fast, which has really boosted my efficiency. The design is very user-friendly, and setup was a breeze—basically plug-and-play with no hassle. The large print volume lets me tackle all kinds of creative projects, from small figurines to bigger models, with ease. It supports multiple materials, and the printing process is super stable with no jams or failures. Overall, the experience is fantastic, and the value for money is excellent—I feel every penny was worth it! If you’re a 3D printing enthusiast, this machine is a must-try!

This 3d printer was incredible. I loved the printer's compactness, as well as its large printing area. This was really easy to use for someone like me, who is a beginner. It prints extremely effectively, and I was able to create a lot of things. This would also make for a perfect gift. The heat transfer was perfect on this product. I recommend this.

Had for not even 3 days and 2 prints and now it’s not printing. I’ve googled every way to fix this and it even says Filament not there when clearly I have an entire roll. This is garbage.

The media could not be loaded. Really happy with this printer so far. The setup was simple, and it started printing smoothly right away. The large print size gives me a lot of flexibility for projects, and it runs much quieter than I expected. Great quality for the price, definitely worth it.

Amazing printer for the price! I started with the Ender 3, but upgraded to the Longer brand soon after because of the not so drastic price but very drastic quality and area difference. It’s a very nice printer. Easy accessibility. I’ve tried other printers from friends, and it seems very very beginner friendly. Leveling is just like any other printer. Print quality is very nice, plus it’s pretty quiet. Easy to adjust the x axis, too. The installation was pretty self explanatory, too. Haven’t had any problems, I would just reccomend getting a magnetic bed instead of a glass bed for beginners. Overall, amazing printer for the price and is a close contender to the best beginner printer!

So far so good. Package arrived on time and intact. Printer was packed well in the box. This is my first venture into 3d printers and my first impressions are that it seems solid and well built. I'm mechanically inclined so assembly was straight forward. Includes the basic tools necessary for assembly. Touch screen is nice and easy to use. Was up and printing in no time. After a learning curve and minor setup tweaks the print quality seems really good to me but again, my first printer. Price vs performance, I would recommend.
