Fuel Belt Helium 2 Bottle Belt - 1st Generation

I've had mixed success with this product. I like to wear my hydration belt low on the hips, just above the pelvis, and I've found that the Helium has a tendency to slide up above the hip bones and around my waist if I don't have it just oriented right. The biggest fault with this model is the silly flask holder straps - it's a 2-hand operation to get a bottle in/out of the holder straps, and this inevitably shifts the position of the unit. On the plus side, the flasks are very easy to open/close, and drink from, and the unit is quite light. The secondary pocket attachment is useful for a car key or gel stash. I haven't used any competitive products for comparison. I'd be interested in trying Fuel Belt's 2nd generation Helium model, see if they've made some improvements to fit and flask holder mechanism.
