Looking for first hand experience, not advice on what to buy/make/use. I have many Eggtimer products and while they are fantastic (especially for what they cost), but the interface tends to frustrate me. Nothing bad at all with Cris' stuff, it's my lack of computer skills causing my grief. I am going to need at the very least a 4 pyro altimeter if I ever get back on track with my LOC Ultimate build. I can muddle my way through all the emulator stuff and whatnot but I find it stressful and frustrating. A hobby isn't supposed to raise my already too high blood pressure. The thing I find intriguing about the Aim Xtra is their claim of usb plug and play. Can anyone who has and uses one verify this?
