I like my Garmin but keep in mind their phone app is a webview, this means all of your data is on their servers. Whether they have an official usage policy you like or not, things can change, servers get hacked, etc. It's possible to use it without the mobile app, but it's a pain.

Cost of electricity is more than x3 in California than Ontario, certainly LA (24-28 cents USD per kWh) vs Toronto (8-11 cents CAD per kWh).
