The UMC is easier to install than the HPWC. Besides the HPWC 2x's cost, there is also the extra cost of installing a disconnect switch which is required for the HPWC due to it being hard wired. For someone with an existing 240v outlet in the garage, the UMC makes perfect sense, provided he/she doesn't plug/unplug excessively and both wiring and outlet are up to par.
For my own installation I used a Hubbell commercial grade receptacle HUBBELL HBL9450A AC Receptacle NEMA 14-50 Female Black 125/250 Volt 50 Amp - Our Item #: 8694, Category: NEMA 4-Wire Receptacles : StayOnline
easily 4 times the cost of the receptacles the big box stores sell. I looked at both, the Hubbell is constructed better. I also used 6 gauge wire and an over-sized outlet box so the wires wouldn't have to be crammed in. I did this so I wouldn't worry about marginal parts being the reason for a fire.
What went wrong with the setup in the garage fire at this point no one can say for certain, I think to much blame is being placed on the UMC.
