Instant delivery. Very good printer. Collect almost no need to collect, everything is collected :) the quality of the print is fine for such a price.
Perfect Packaging, free rapidissima, assistance to the store at the top, product great for the price range at which I bought! Mount rapidissimo, you lose only so much time to level the floor after the first prints, that with using it stabilizes the whole structure. I am really enjoying, simple to use. You can count on the support of groups of assistance as per specifications Longer. Advice for someone who does it start.
Got the printer. Came almost completely assembled, it was only necessary to put the frame with the extruder and Z axis drive. I spent the first seal, everything is very good, I'm happy. The truth at the first print stopped clicking the end of the z axis, but so far it seems it works. The reason is not yet clear. The printing quality of the box is good!
All perfect and amazing delivery time
Great store very fast kind and professional. The merchandise is perfect and works well.
Came for 3 days very quickly collected in an hour and immediately to print from the flash drive in Super thanks
Everything, Everything, at a high level, I recommend definitely, thank you all.
E' la mia prima stampante 3d, montata con calma in 30 min, livellato il piano e subito in stampa un file demo presente nella sd. Qualità e velocità più che soddisfacente. Plauso particolare alla piattaforma AliExpress, da negozio CZ mi è arrivata in 5 giorni... e dire che usavo solo Amazon!
Excellent printer for your money! It's very simple. The drivers are really quiet, with the possibility of replacement. Requires careful assembly of the frame at the corners and broaching of all fasteners (one-time procedure). Prints can be said from the box. There is a video assembly instruction and a native slicer. The cooler on the mother is really noisy, I advise you to immediately replace.
All ok
Delivery in 3 days .... Very good. Now we go to editing.
3 days shipping to Germany. I was unlucky enough to get one of the motor drivers fail after about 2hr printing. Getting in touch with the support from Longer's official webpage helped me get a new driver shipped to me. After I installed it the printer is working great and producing great results.
Super fast delivery. Product very well protected. Need 40 minutes to mount the printer and make the necessary small settings. The instructions are very clear, excellent printer to start in 3D. Taking metal extrusion is a necessary luxury. For the price, I recommend!
It came quickly. Going easy. Configured and launched quickly without problems. My first printer on this for me printing is acceptable.
To start it is a very good machine. It is very largely pre-assembled, the most difficult was to set the z switch. By cons it is necessary to reformat the sd card provided, otherwise the impressions do not start. Delivery in 48h Neat packaging In short everything is fine
Looks like the printer was in the warehouse for a long time. Plastic rollers of extruder movement changed their shape. The extruder moves with periodic stops, corresponding to the 1st turnover of the rollers.
The printer is good, prints out of the box but there are small jambs, the type of noisy cooler board and not working normally connect by cable but for this it is possible to get to get kitaec Budet predlagat ispilzovat izolentu no ne soglasivchis mojno vernut 3K rubber
Принтер очень понравился. Очень быстрая доставка. Продавца рекомендую. Только вентиляторы шумные, как все говорят в отзывах.
The printer came quickly, an order from Russia to St. Petersburg. All in their places, everything is whole and of good quality. Collected, handed, connected in an hour. The printer came almost assembled, there was no problem collecting it. Prints well. Price and quality at altitude))
The printer came in 6 days! Packed very well. After the assembly, everything immediately earned, without any Dancing with the tambourine. I'm very pleased with the printer. Seller recommend.
Cool thing. Here we are.
Ordered on a Tuesday and received on Friday warehouse france. It's my first so not easy to adjust the ideal tray and ask someone who knows and take his time. Very good printing quality. A 5m pla sample is offered.

Came quickly, collected slowly on video, everything works. I'm happy)
The cooling valve is dead for 5 minutes. The rest works so far without problems.
