I bought this harness because I liked that my partner and I could both use it, given the adjustability of the straps. It easily accommodates my wide hips and her narrower hips, but when I say the velcro is loud, I mean it. It's very secure, which is great, but as a result you hear a very unpleasant ripping sound when you separate the pieces to adjust...which you inevitably have to do multiple times, and then repeat for the other side. It's a major buzzkill, and loud enough to be heard from another room. But it's important to get the straps lined up right, because if not you or your partner will be subject to very scratchy velcro on your skin. It also is "thong" style, so be prepared for the strap to wedge between your cheeks. Not a negative, just a Thing To Know.
All that said, it is functional above all, and quite easy to clean with diluted vinegar. If the straps are lined up, it doesn't chafe. It's a bit of a struggle to get in place, but with some elbow grease the Flurry O2 fits adequately. The base is a bit tapered, so it's not the sturdiest, but that shouldn't be an issue with a dildo that has a more clearly defined base edge.
The one thing you can almost always count on with any sort of strap-on play is the amount of time that is going to go into getting the harness on and everything situated properly. It can be easy to incorporate that into play, but sometimes it can be a bit of a mood-killer. For the times that you just want to skip the formalities and go to town, this is the perfect harness. I typically use the Mark or a Pack n Play with this harness, and they fit perfectly.
The velcro is super strong and easy to adjust, and I haven't had a single problem with the harness coming loose or adjusting during play. My only problem with it is that I have slightly longer labia, so the strap that goes between my legs (even with as wide as it is to avoid this very problem) can pinch a bit. It's easily avoided by me wearing underwear in addition to the harness.
At first, I was a little concerned about lubricants staining the white garment leather, but even with extensive use with water based and silicone lubricants, the leather cleans up beautifully and hasn't stained a bit!
All in all, I absolutely love the Nurse harness. It's beautifully made and will last a lifetime!
