"Item seems nicely made, I expect it will stand the test of time. The description was a bit vague and slightly contradictory so I'll tell you what I received: Packaging marked Rothenberger No 7.0951. A 'main body' and a total of three cutter heads [for 3/8",1/2" and 3/4" flat valve seats] and nothing more. Rothenberger's web site shows a photo of it with a vastly different threaded adapter and a total of five cutter heads, possibly the extra two would be for conical valve seats?. The photo and description on this site shows it with 2 seals [tap washers?] which didn't come with it, although I didn't particularly want them."
"I did not see the point of having two seals supplied and paying extra. When I bought the item by choosing it from the catalogue, there was no mention of seals, I assumed they were reseaters. I returened the item and bought the alternative. Buy this one: Plumbing Tools by Rothenberger Tap Reseating Tool Product Code: 57400"
