Tested the 0.4mm red version and I bought 3 pieces in a roll. Very grippy and spin-sensitive when new, but after put the rubber on the dash board of your car, leave it under sunlight for a few weeks, Bang! Got a completely no-grip slick top sheet which is as slick as those German brand posh antis.
IMO the top sheet is quite hard after the treatment, press into the rubber would not make dents that remains for a long time, and the top sheet would not absorb much energy from the incoming ball, blocking and flat hitting with this rubber feels like doing it on a naked wood blade, the speed and control depends on the wood blade rather than on the rubber. When glued on a 8mm balsa core blade that offers mid-low catapult effect, blocking and hitting is almost as fast as an offensive pips in rubber, control was just ok and was hard to do short blocks at close range, balls go into the net or over the table sometimes if the blade is not at the right angle. But while glued on an ALL- blade, control was much better and was able to do short block easier, more chance of the ball to go to the position that I am looking for (greater margin of error is allowed).
Spin reversal issue is funny: works well on old 40mm ball, no good on 40+ plastic ball, only a little bit of back spin is sent back to the opponent when blocking against looped ball, and the ball is much more like a no spin dead ball.
For quality, like many Chinese rubber, after stored for a while, even unopened in original package, the sponge shrinks and makes the rubber curvy like a tensioned pips in rubber (the 3 Guards I got a 2011 and 2012 date stamp on the sponge). Also, some of the rubbers comes with edge which are not in a straight line .
In conclusion, this is a grippy attacking anti good at close range attacking and lifting back spinned ball. The full potential of this rubber is reached only with treatment.

Giant Dragon Guard wasn't what I expected from an anti. I expected a top sheet to be slicker like Butterfly Super Anti and most other EU/JP antis but GD Guard does have some friction. I bought the 0.4mm version which I think was a mistake. The top sheet is relatively hard and the sponge is hard too but it absorbs energy. You can depress the rubber and see that it takes time for the depression to disappear which is good for an energy absorbing anti. A 0.8mm sponge would absorb more energy.
Because the top sheet has friction one must play with more active strokes and learn to close the paddle more when blocking spinny top spins. I believe that control is in the user but that said, this anti is easy to control. One can chop or chop block with GD Guard. My main complaint is that 0.4mm sponge is not enough to absorb and block a hard loop at the table. Get the 0.8mm or thicker if it is available.
Note, I have played with GD Guard, Yasaka Anti Power, Nittaku Best Anti and Butterfly Super Anti. My favorite is BTY Super Anti.
