14wntrI would defer to MassDrop for the return policy as MassDrop is the seller. Here is there return policy from the Help Center: "We only offer returns for items that arrive damaged, defective, not-as-advertised, or are missing components. When drops are completed, we submit the group's order to the vendor up-front. This is how we are able to deliver the best value to our members and is why all sales are final. In the event that a product arrives damaged, defective, or not as-advertised, please contact Massdrop Support and we will assist you. "
With regards to the warranty, RapidX offers a 2 year manufacturers warranty. Thanks!
