Thank you so much for this post. I received mine last week (took about 2 weeks to reach the UK) and they are AMAZING. Binds so much flatter and more naturally from all angles than my T-kingdom one which cost about 6 times the price. Extremely comfortable as well due to the stretchy elastic strips on the side. Only con is that the seams on the left (near the elastic bits) stick out quite a bit especially on lighter fabric. But if you get one in a darker colour or wear a shirt over it, it's not noticeable. The product pics show an obnoxious logo around the upper back area, but the ones I got were totally plain, thankfully.
I was in between an L and XL so bought one of each, have not tried on the L but the XL is a great fit for me (I am Oriental, 5'2, 68 kg, probably a C). Initially I thought even the XL on the largest setting was too small. But the trick to put it on easier, is to rotate the inner binding layer slightly anticlockwise so you can reach the hooks easier, and to first focus on stretching the elastic straps as far as they will go, while doing up the hooks (puffing out the chest helps with handsfree stretching). Once all the hooks are in position it is easy to reposition and squish the boobs down and out. With that technique the XL on smallest setting is perfectly comfortable.
In summary, these are absolutely amazing for guys within their size range. It's a shame they don't make it in more sizes as I think the design is ingenious. Worth at least 3x the price.
