I think the Statik system is great, but I didn't realize there were two speeds (my bad) why would anyone want a slower charging speed? My first 2 cables did not work and the 100 watt charger had a broken connector. I wrote customer service and sent pictures. Over the next month or so I re-emailed. I got no responses.. I eventually bought new cables and charging blocks. Then after months I received all new stuff from Statik. Yeah!! But I can't return the others. And now that I know about the blitz charge, why get the slow one. So very cool product.. just really poor communication.
