Need advice about this 3in1 endbag

[GhostFighter]

I want to get a double end bag for home but i dont like it that im not able to do the uppercuts on them wel, untill i saw this thing and it comes in PU and leather: [IMG]http://i465.***********.com/albums/rr18/Mortyr79/site61_20081211171723_1_l31bokszak.jpg[/IMG]
Could this be as good as a normal double end bag or will it provide me a different workout?

it seems like it will throw off the timing compared to the traditional double end. maybe you just need to work on your speed and timing if you cant throw upper cuts on a conventional double end bag.
