Miri - When you have the chance , I would definitely recommend an upgrade to the US25. I'm pretty new to the saber scene, well custom built saber scene anyway. I've got a fairly large collection of Master Replica sabers so I know what those boards are like. The US series has that cool flicker effect and very sensitive clash sensors. The run time on the built in rechargeables was awesome on the Precipice too. I know it was longer than an hour, though I never timed it. Having a recharge port in the pommel is a nice touch though. Adds a little more "Star Wars" to it in my opinion.
GG- Cram Fu Master, Miri is dead on. I would shake the precipice with it off and all I could here was the switch and the d-ring. Nothing moves, nothing rattles, it was great. I wouldn't change a thing about it :) When I got the saber, I said to my wife. "You know, I wish I could have had a purple blade with this one, but that wasn't an option. They sure look cool. And I bet this would look great in gold and black too." I considered a couple of options and submitted some renders and the Precipice v2 was born. I'm excited about the upgrades to the Luke v2 as well. It's a very nice looking saber. It seemed much louder than it was before. Before long, I'm going to have to build a display case :)
