To be the third brand I tried, I was pleased with this product. Good fit, fabric is nice, good suction effect, appropriate size, no leakage, no discomfort even at night or while playing sports. I just regret the lack of a carrying pouch (a small cotton bag for the purse) and a manual delivery (useful for beginners). The stem is quite uncomfortable compared with other brands, but it is somewhat annoying since we always end up cutting it pretty quickly!
