I'm glad I came across this thread. The last couple years I've been using one of NiteRiders entry level rear lights. Because of the reviews and statements regarding the CYGOLITE Hypershot 350 I decided to go for it and pick on up. It was delivered just a few minutes ago and all I can say is WOW! The 350 lumen capacity of the Cygolite compared to my 80 lumen NiteRider is (excuse the pun) like day and night. I'm sold.
