I used to be like you and cared a lot about any imperfections. It just takes so much out of me to care that much anymore. There are some puckering and unevenness on my custom G5s but I only cared about it for 5 seconds. As long as it stops the puck well, and does not detract from the performance, I would not be worried about the cosmetic side of things. On that hole on the glove though, it might lead to faster wear - though I don't think the wear will be terribly heightened.
I would say there's nothing wrong with you sending it back - it should be perfectly fine under the return policy right? I don't think these were custom ordered?
