I ordered a pedal from an online retailer that was listed as brand new, but arrived with the seal on the product box cut open. The pedal itself has a couple finger smudges on it but no wear and it seems to work okay. However there's a sticker on the bottom with a serial number that looks like it might've been peeled off and stuck down again. I'm not certain of that but it does look odd. My question is, should I return it and ask for an unopened one or just keep it? On the one hand it functions, but on the other hand I like buying new pedals so I don't have to worry about getting one that's been kicked around, dropped or otherwise abused. I also know that a new pedal will have a full warranty.
