I picked one up recently just because it's not too expensive and I wanted to see what it was all about. I'd classify this knive/combo package, as a "TIFWIW" (Take it for what it's worth) package. Not that it wouldn't perform under strenuous circumstances but it's not the most robust knife I've seen.
Now - I haven't used it in practical situations yet, but here's my observations having one in hand.
The knife is ultra light, which is great for just throwing it in your pack/bag and not noticing any extra weight. How the skeletonized blade performs under stress would be curious to me. I can see it performing light to medium tasks with ease, but get into any heavy tasks and you might be better off with a more robust knife. but again, it seems like a tradeoff of light construction vs. strength. The G10 scales are actually quite nice considering the skeletonized nature of the handle/knife. Good grip and size for my hands (I'd consider that I have normal man size hands - gloves are L or XL), and it is well balanced, just feels good in the hand.
As for the sheath, yes it's not the strongest constructed nylon sheath, with velcro as the primary means of holding the sheath to a belt. The velcro retention strap to hold the knife in the sheath leaves something to be desired, it is a flimsy part and it is only the velcro holding, no button, and after about 20-30 removal/replacements of the knife it seems to be losing it's "velcro catching ability". The pouch with the firesteel and whistle is a nice touch. The firesteel is the Swedish LMF Firesteel Mini, so it's small, but in a pinch I'm sure it would be fine and there is a notch in the back of the knife that fits the mini firesteel perfectly. The whistle is a whistle, loud, but small so high pitch - would obviously be better than yelling for any length of time.
Overall it's a nice little package but I wouldn't take it camping as my primary knife/firestarter/survival knife, although if you're a climber and weight is a top priority it's not a bad choice.
I also found some Youtube video reviews that are pretty comprehensive so here's the links:
