So first things first - the company is not afraid to add a personal touch to their orders. When I had made my order, the form asked for an optional note if I wanted the staff to know anything. I mentioned it was my first binder, and when I got my package, they included a postcard with a handwritten note saying they hope I enjoy my first binder! This is a really nice personal touch and it made my day!
As for the product itself, it's my first binder so I don't have much to compare, but I have a fairly flat chest already (B or C cup depending on the bra), so I didn't need much. It was very comfortable and I had zero issue breathing with it on. The material on the back is a bit stretchy which should make it easier to fit. Getting it off and on definitely got easier after the first few uses.
I personally really like the style of crop-tops, so this works great under an open jacket for me. However, it was a bit short in my opinion, it could use a band on the bottom under your breasts. I actually think that would also improve the compression, as I found that it tended to have a bit of space between my skin and the binder at the bottom which let my breasts come out more. Then again, the pictures showed it going a lot lower on the models than it did for me, so this may be impacted by the fact I have broad shoulders and my upper back has a bit more curve to it than the models (minor medical issue/skeletal structure).
Since I am non-binary and aiming for a more androgynous appearance, the level of compression was fine for me, but someone who wants a flatter chest or with a bigger chest to start with may need something more compressive, as I'd say it reduced my chest to maybe an A cup with it on.
I have a chronic illness that makes me very sensitive to hot temperatures, so I may not be the best person to ask here, but I'd say it does a decent job of keeping you cool in hot temperatures. Not quite as good as my favorite sports bra, but about as good as the average sports bra probably.
I did have a little bit of trouble with positioning my breasts under the binder, as whenever I positioned them towards the armpit (as recommended) it resulted in very large, unsightly bulges of skin under my armpit. I think this could be fixed by having the bottom of the arm hole go a bit higher, but overall it's not a huge issue if you are wearing something over the binder.
I'd say overall, this was a really great first binder for me, and most of the improvements I'd make are likely specific to my body. It was very comfortable! If this is also your first binder, I'd recommend trying this and if it works for you, you can always move onto something more compressive in the future!
