I have my reservation since Feb 2017, it is more than 18 months now. The only thing still keep me in the reservation is the fact that I locked in the price before they increase the PW2 price. Looking at a lot of complain about Customer Service, I'm highly consider looking at the LG Chem, which is gaining steam. My solar installer is doing the same thing because they get a lot of requests for home battery but Tesla can't provide them the product to sell/install.
The sad truth is, we all give our $500 to Tesla for more than a year (some are closing to 2 year), and we are not incurring any interest that we "loan" to Telsa! Looking back if I spend that $500 to buy Bitcoin back in Feb 2017 I would have $4000 before Bitcoin crash in Nov 2017, and as of today I would have $1200 worth of Bitcoin. That's the punch in the gut for me! The more I look at it the more I hated Tesla than a bank, at least bank give you tiny interest, nothing from Tesla!
