Menu speed and loading time is pretty good. Remote has drained 3 sets of batteries in less than a month. There seems to be a glitch when exiting Sling TV and then starting Netflix the stick reboots.
I mainly use the new Roku Stick for Netflix, and comparing it to my old Roku, this is an unfortunate step down, but it may have more to do with the Stick accessing a later version of Netflix than my old Roku. Searching is more difficult, the buttons don't work intuitively, and the movies no longer play through the credits. Other than that though, excellent.
