Before I start I rated durability at 3 because I ordered these for my dad, he received them today, and we need to see how they hold up.For roughly 40 bucks my dad was thrilled to find these. When they were delivered he went out, pulled the old bars and put these in. He reported they all fit, all were in food shape, and he was impressed with quality.While I think the porcelain coated versions would hold up longer, I think these will be food for a few years.I will report back after he has used them a few times.
