Several points to touch on.

First, this isn't "B-2" brand. It's DBoys, their copy of the ARMS #40 rear sight. That said, it's a decent cheap flip-up BUIS.

Second, the QC is a little off. My rear aperture was crooked because DBoys couldn't drill a straight hole perpindicular to the side of the unit, and as a result the angle of the screw which allows side to side adjustment was a bit off.

Third, the paint is incredibly low quality and will wear off rather shortly.

For the price, I highly recommend the Samurai or Action flip up rear sight, which are also copies of the ARMS #40 and is available from most Hong-Kong based shops with airmail shipping being roughly the same. Both offerings are also much higher quality.

Finally, the spring which held the retainer lever in place on mine was incredibly low quality and no longer functions quite as it should - the rear sight is held down when folded compactly, but I'm not impressed with the overall quality.

I hope this helps you to make your decision about buying - it's not a bad sight, but for the price point it's also not that great.
