Help to buy lube for the first time

This will be my first time buying lube and I'm really unsure about the one to choose. I want to use it with my silicone toy, so it should be water based. I want it to be safe and of good quality, since I don't really want to have a reaction. I read the reviews and it really seem to be about personal taste,but I would love any opinion that could point me on the right way
