You have gorgeous breasts!  I have tried the 180 and 210 ml domes from Ali Express.  I modified them with check valves for use with a hand pump. Without silicone rings, those domes are very uncomfortable to use.  The most comfortable domes I have used are the smaller cheaper ones that come with silicone rings and a hand pump.  They are sold under various brand names and are available for around $20 on Amazon, and even less on AliExpress. I was able to wear those for hours without any discomfort. Unfortunately the tops of the little green release valves break off easily, but that does not affect the efficacy of the domes. I only wish that the Chinese manufacturers would offer the same package in larger sizes.
