Query: Not like they used to be

This is a review of the comb itself not the vendor who sold it to me. I have no quarrel with them.I have used this type of comb for many years prior. I have psoriasis and this comb was an excellent aid in keeping the scalp plaques and flakes diminished. I bought two new combs becuase I had lost my previous one. The previous one had lasted me for several years with an occasional tooth breaking off.The new combs I ordered were a major disappointment. With the first use, the teeth of the comb started to bend and distort permanently out of shape. The comb became useless after the first use. I tried the second comb hoping the problem with the first was an anomaly. It was not, the second comb suffered the same problem with the first use. Perhaps these combs came from an overall bad batch. I will have to think twice about purchasing thes again.
