bought 2 units for my P1S and A1 after saw all the good review out there. The manual is not really good to direct how to set up. But as the owner of 3D printing, I believe most of us already have a little bit of knowledge of computer. But, this is a very usefull thing. Biqu have a great job to make Bambu lab printer a little bit customable for us. The panda pwr can turn off my printer if it is finished printing, even turn off my additional lamp, show me the current usage of eelectricity and the log of usage. I hope biqu will add more usefull in the future forall their panda's bambu lab. I've already have the panda touch, panda lux (P1S and A1), panda pwr... all really great and very usefull.... even the support really helpfull when I have a bit of trouble...
