First impressions out of the box is that its an amazing product with a small footprint and super light weight.
For those that have never upgraded before be prepared to print parts to not only mount it but to cool the filament as it comes out of the nozzle. I did print without cooling and the results were not great. I have since added a fan to cool filament and its a lot better. Happy with my purchase :)
What's said about spares is for sure spot on and if I could take out 1/2 a star for this I would. BIQU needs to get the spares up on their site ASAP because if for any reason the nozzle gets damaged its just not available right now. I have contacted BIQU about spares right after receiving it and was told they will be available soon (when exactly?)
That being said I do love the product and will recommend it to those who are looking to step up their print quality and especially printing speed.
