I recently picked up 3 Mpro rda's from Aliexpress. In canada, you can't source them as they've become 'illegal' due to not having a 'childproof stamp' (really?!?). Any sites like wish (US) won't ship them to Canada. Ali was my only possibility. They came faster than expected and work well with Vandyvape mesh (I'm using 200). I recently discovered a much better way (less loss) to load the mesh- take a small piece of parchment paper and fold it in half. Open it and put it on the scale, turn scale on or tare, then weigh your spice. Then put the amount in an area on the parchment about the same size as mesh. Fold the parchment in half and squeeze the spot of spice. Open it again and use a dab tool to place your 'pill' of spice on mesh, then light shots of heat to melt.
