I have an MB-D10 clone for 2 months and I am very happy with it. I know the original will be better and it is sealed, but is very expensive for me. I ve buyed the "DSTE MB-D10" on ebay. If you want look for "DSTE MB-D10" on ebay and there are a lot of options, with batts, without them, etc. I have bought for approx 50$. The model I have does not have the Infrared; the current model will be more useful because of this. The grip is not sealed and the wheel that adjusts the grip to the body, when the grip is fixed has a little movement, but the grip is hardly fixed. The other things about this grip are all good for me.
