Used spectra pump..?

Would anyone buy a used spectra pump? I just bought one two weeks ago and have realized that breast feeding just isn’t working out for me like I had hoped. I have the pump, all the bottles, a carrying bag and a cooler. I also have brand new breast milk storage bags and Mother’s milk tea/milk flow drinks. I hate for it to sit around not being used and was wanting to post it for sale on Facebook. Do you think anyone would be interested or is it gross??? TIA!!

****I’m not trying to sell this here or to anyone. This isn’t an ad just looking for advice before I make a decision. ***
