Originals lasted around 4/5 years. Helped my Call of Duty greatly (the good ones, Modern warfare remastered) doesnt help you fly a jet pack. Good thing both of my bikes are aluminum so I dont have to worry about rust, but it would be nice to see a thick rubber pad built into the cage to protect the finish of the bikes. Not knowing the terrain really slowed her down. The battery lasts a solid workday (about 10 hours) and I can have a solid connection to my PC to about 40 ft. From the opening scenes, which has some amazing cinematography to the final scene I was pulled in. An hour and a half later, I was 20% through and sadly returned the book to the display table. I was concerned about fit and comfort but these are great. I wish I could capture in pics how the sun reflects and the case glistens! Home run, Dr.
