Query: great product

Excellent, high-quality product so far! Very solid build, very strong but compact, shell stays cool, thermostat is accurate. Gentle radiant heat does well for sub-tropical plants! Only complaints: a remote would be cool, and it idles constantly, putting out unneeded heat in small area (costing $). Price is a bit high, but very worth it if you need reliable heat!
