It is, definitely. We own our home and leave it on the level 1 charger all the time. It gets us around the metro just fine, no long commutes so it's great for us. And as someone mentioned somewhere around here, a longer charge time isn't necessarily bad if you're the only driver on long trips. I'm honestly more worried about having to stop in areas with only a couple chargers (Midwest here) and some asshole vandalizing them and leaving me stranded. But that's a concern that pops up once or twice a year at best. And the various charger apps are pretty good a letting you know they're down.
