Hello;
I haven't seen any reviews about those speakers either, but I can tell you a few things to make your choice easier:
1. The speaker sets from Hercules are usually in the "best buy" range, not "High End" nor "Dead Cheap" either, but somewhere in between.
2. I have a pair of Hercules speakers, the old XPS 210 range. They offer quite good quality: They are far better than the Labtec speakers which I also have, but not as good as my most expensive speakers, the Altec Lansing 621, which cost 3 times more. Anyway, My Hercules speakers are perfect for watching DVD, playing games and even listen to music.
3. There is 1 thing you should bear in mind: the sattelites of the XPS 5.100 use so-called neodymium drivers. These drivers are good enough for playing games or even watching DVDs, but for music, their sound is a little "thin".
Because of their small size, they cannot go low enough, so there will always be some kind of "hole" between the frequency range of the sattelites and the range of the subwoofer. This is the same for ALL speaker sets which use these tiny neodymium drivers, regardless of the brand name.
4. Finally, I have heard the XPS 5.100 in a store, playing a game. They sounded quite convincing and have more than enough power. But you can hear that they use neodymium drivers. There is a (small) hole in the frequency range of the "high bass", say at 150Hertz or so.
Conclusion: If you only want to use them for watching DVDs and playing games, then I would say "go for it". For this purpose, they are very good, although not as good as "high end" pc speaker sets, such as the Altec Lansing 651 which cost more.
If you want to listen to music, then I would recommend you NOT to buy speakers which use neodymium drivers for the sattelites, regardless of the brand name. For music, larger drivers in the sattelites are much better.
Don't hesitate to ask further questions.
Happy Christmas!
