#Sonic Pad I have to say this the Sonic pad has caused alot of hype. I have one and was not able to setup as sensor had an issue, contacted Creality and they shipped a replacement sensor over within a week. They were quick to respond to email, follow ups, and man Im loving this ..... I would love to have another one to use with my S1... Its a learning curve but it is worth it..... It is a huge investment as i am starting up a printing business and every minute helps with great printing quality.  It would be great if I was able to own another Sonic pad to boost my production and sales...  Thanks Creality for the awesome response and customer support on the faulty part.
