Any thoughts, insights or opinions on the ClipperCreek HCS-40, 32 Amp Level 2 EVSE, 240V versus the Siemens VersiCharge, 30 Amp Level 2 EVSE, 240V? (*Hardwired, outdoor install.) The price for the Siemens on Amazon is currently $136 less than the CC. Bottom line...is the CC worth the extra $? Thanks.
