We've had two of the professional, expensive ones and we've broken both. The first forgot the brand, one of the plates stop[ped working. It was supposed to have a 3 year warranty, but we couldn't find the papaerwork.

SD dropped the current one and broke the ceramic plate.

We were very pleased with both of them.

We had originally gotten a bottom of the line, conair and it doesn't work well at all (but it does still work)

So what about size....is 2" better than 1"
