The last time I was on the phone ordering my red Kitchen Sink I mentioned to the sales guy that my PB2 could do with some new ear socks and nose bombs. He said he would send me out some ear socks right away but the nose bombs were backordered so they would take a bit longer. A few days later I get an email from him saying that the PB2 could only get new rubbers by sending it in. Not wanting to lose it I declined. Well today I got the new nose bombs. I was shocked. So I'm looking at the paper and I see the sku OO9127. Well that's not a PB2. PB2 is OO9137. I checked and OO9127 is a Pit Bull. So I compared the nose bombs on my PB2 with the ones on my Pit Bull and they look to be the same. The new ones look like both of them. Any thoughts? Either way they were free and unexpected so I can't complain.
