I've gotten used to treating portable elextric heaters as disposables. Last year I decided to buy another heater based on my guess that it was about time for my old one to die.
About 6 weeks ago it did. I started using the new heater, which was a Holmes. It worked fine for a few weeks and then wouldn't heat past 60F.
I emailed Holmes and told them what had happened. I had no receipt and didn't even know how lond I'd had the heater. The model wasn't even listed on their website any more. All I wanted to do was let them know about the problem. They returned my email and asked for a date of manufacture code that was on the plug and I sent it.
Today I received another email - they're sending me a new heater for free! Now that's service.
I still think portable heaters are disposable, but you can bet I'll buy Holmes from now on. I suggest you do the same if you need one.
