Econo High Power Compression Chest Binder Tank

TBH I kinda love this thing.
BREAKDOWN:
Fashion: 2/5
Function:  4.3/5
Comfort: 4.7/5

This is the best binder I've had, and I've had quite a few binders. It's the most breathable of anything I've ever owned; I barely sweat in it at all and can almost forget that I'm wearing it through the duration of the day. It gives the appearance of smaller pectoral muscles (with a B/C cup starting) and has decent tummy flattening capabilities (but don't expect a miracle). Keeps everything in place well.
For the money you'll spend for this, there is no reason to hesitate. This is the **perfect** item for first-time buyers or anyone who just wants to try it out. I seriously cannot stress the comfort of this thing. You will have to wear it under something, as it's sheer, but I have no problem concealing it under a shirt.
The one thing I will mention is that it does tend to be slightly irritating in the underarm area and a bit around the neck because of the nylon material, but it's nothing slight adjustments won't fix, and it's worlds better than anything else I've ever tried.
One final bonus: it doesn't pinch around the ribs, so you'll be able to take full, deep breaths instead of panting all day and getting headaches because of air loss.  
Seriously, buy this, guys.

I'm a genderqueer person who wanted to experiment with minimizing my breasts than making them look nonexistent. Because I don't really have dysphoria over my breasts and more just wanted to try binding out, it made sense for me to pick a cheaper binder over a super high-quality one. I would recommend this binder only to people who are in similar situation. The fact is that nothing is going to make me look flat chested (I'm a 36DD), so I am satisfied with the level of compression even though it's not super flat. My main issue with it is rather the fact that the compression material goes all the way down. When I made the purchase, I thought that this would be a positive because it would flatten my tummy and hips more evenly and make my figure more masculine. However, the material does not hug my body under my breasts. Within minutes of wearing it, it all rolls up around my waist no matter what I do to try to secure it. To try to fix this when I'm wearing form-fitting shirts, I usually pull the bottom part over my breasts so that it covers about the same area as a sports bra would. However, this tends to slip down and you can see where the fold is over the shirt. On looser-fitting shirts I just let the material bunch around my waist and it isn't noticeable over the clothes. This is not a huge issue since I bind very rarely, but would be a deal breaker if I wanted to use it to bind on a regular basis. If you have wide hips and a small waist, I would consider spending a little more for a binder that will fit more securely.
