I've completely switched to 3D printed mesh saddles. I shift my saddle position based on either climbing or sprinting and the minimal friction from the mesh design helps. Also living in year-round riding weather, the saddles don't absorb heat staying cool even on the hottest of days.
I've been able to return items that have 15 day free returns. In the US, items get shipped back to a domestic warehouse. AliExpress then refunded my money once delivery was confirmed. For US customers, double check the return label though. The online system will say USPS, but the label will be UPS! I accidentally dropped my return to USPS. The item sat for 4 days, but luckily I was able to retrieve my package because my local PO was just holding it and I asked for my package back so I could drop it off at the UPS Store.
