I've used the Campmor cape for four years of commuting in spring/summer/fall. My feet and lower legs do get a bit damp during long and heavy downpours. I prefer this to getting soaked with sweat anyway, as I do when I wear anything with more complete coverage. In the winter, during cold weather (<40F), I avoid this issue by instead always wearing a gortex shell (with pit zips) and bringing along breathable rain pants to be used when needed. The "breathable" gear does not vent well enough for cycling, of course. In the cold weather, I prefer warm sweat to cold rain. Neither the cape nor rain pants is a good solution during melting snow, which I experience pretty often.

The Campmor cape has thumb (wrist?) straps and a waist/leg strap in the back. It does not flap much, even during high winds. I do use caution during high side winds, since I do have more of a wind profile than with a rain suit. There is more wind drag from a cape than a rain suit at all times. The increased drag does slow me down some, but I prefer to be a lot more comfortable over a bit faster. Be warned-- the increased drag would likely drive performance-oriented riders nuts. It is easier to take off and put on a cape than a full suit, so I can more easily put it on/off and on/off during those common periods of intermittent rain. This reduces the drag penalty somewhat.

The hood is well cut, so I can wear it under my helmet without obscuring vision, even when looking over my shoulder. I only use the hood below 50F, since it is quite warm.

The Campmor cape is lighter and more compact than some other options. In fact, in spring/summer/fall I just leave it in my commuting bag all of the time. I'm always prepared for rain and I'm not a slave to weather forecasts when leaving the house in the morning.

Finally, I'm a high-visibility rider. The Campmor cape is bright yellow exactly when I need it most, during overcast days when drivers have rain-covered windshields.

I haven't had any issues with leaks of my cape, nor the two capes I bought for my wife and son. I can imagine some seams leaking, though. This is an inexpensive product, so I doubt the seams are taped. If I did experience leaks, I would probable just seam-seal them with the sealant mix I use for my ultralite camping gear.

I have never tried any other cape, since my Campmor meets all of my needs. It will not last for decades, like some of the more expensive options. I'm sure there are other good options out which I haven't tried.
