I am looking at these 2 ESVEs. At Costco, they are doing a $70 off the Versicharge. This brings it down to $390 before tax. The Juicebox Pro 40 amps is faster and sleeker. But it's also priced @ $550. I read about some charging issues between the Versicharge and the Model 3. Has that been sorted out? Any suggestions on which one to get? The electrician will be coming to install the NEMA 14-50 outlet for the Juicebox..seeing this deal on the Versicharge is making me reconsider. Any advice would be much appreciated! Thanks!
