I received my tungsten steel nozzle assortment in an unbelievably short amount of time (got them in a few days and I have waited over a month for other items sent from the same vicinity).
What I really want to comment on though is Sovol's overall product and after-sale customer service, which is the best that I have ever experienced (and I have experienced a LOT in my 70+ years). My sons bought me a Sovol 06 for my birthday and after about 20 prints it froze and required a reset of the printer (which is not possible). I am both a mechanical and electrical engineer and, with Sovol's help (via prompt email responses), we diagnosed the problem to be a failed motherboard. They mailed me a replacement which arrived almost immediately and after installing it, the unit ran flawlessly and has been happily printing ever since.
The quality of Sovol products is phenomenal! My sons and I (all of whom are engineers), constantly marvel at the engineering design, ingenuity, and integrity that goes into their builds. These things are practically bullet-proof!
I will continue to patronize Sovol as long as my old age will permit (luckily, it's a hobby that doesn't require a lot of physical exertion!)
