I have been using the commuter mask for a few weeks now and I have to say I feel much more secure in this than in a cloth mask (or disposable). It fits really snugly around my nose and mouth and it's flexible enough for this to feel fairly comfortable. Glasses don't fog up at all when I'm wearing it. Breathing is very slightly more effort through the filter (proof that the mask really is pretty air-tight!), which is no problem at all for me but noticeable for a relative in her 70s with weak lungs (it's ok for her just sitting in a taxi, say, but not with any kind of exertion). I feel so much safer going into shops or standing near people who are unmasked when I'm wearing this kind of mask. If you want to protect yourself as well as others, I think this is a really good option.
We are retired therefor not going out often. We find the mask and filters easy to use. You can wash and dry mask in seconds.. unlike the cloth ones. Filters easy to breath thro and quick to change. Good product.
Masks feel secure, hold to facial contours, a little condensation now the weather is colder, but I still feel happier wearing one on the tube than a less substantial item. Filters easy to change, one of the two masks I bought is a little loose on the front and can fall apart whilst putting on or off, but overall a good buy.
