In this photograph, you can see the second of Newgy's little tweaks to the Pong-Pal - it pulls apart to make transporting it around more convenient. The upper tube fits snugly into the lower tube, and pulls apart with a little upward pressure and a small twist. If you look closely, you can see the slight widening of the opening at the top of the lower tube, which makes assembly and disassembly a breeze.
The third adjustment Newgy has made is to angle the bottom of the Pong-Pal, making it much easier to use the Pong-Pal to pick up balls that have rolled under the table or under chairs, while still being easy to pick up balls normally. Again, a simple tweak that makes you wonder - "Why didn't I think of that?"
