Electric Kilns for Heat treating

[Fadcode]

Just wondering if anyone has one of these kiln's advertised on Ebay, they look ok, but was wondering if they are in fact worth a go.

Price and specs seem to fit,

Looks rather small to me.

Agreed a little on the small side, the depth is the critical one, but at 11.5 inches, and 14 on the diagonal, doesn't seem to bad for the price, the height and width of the chamber being a bit smaller, would probably mean faster heat times and less cost, I think.
Based against the Evenheat, and Paragon similar sized models which are 3 times the price.

I wouldn't recommend this for firing pottery, but I guess you have something else in mind.

Heat treating knives, of course.
