Some of the devices come equipped with a Simple Remote. These lack TV controls (Power and Volume) so you must use your TV remote to control these functions. In the current line of new Roku devices, limited to the HD Roku Express.
In Roku model releases, generally the non-plus(+) models come equipped with a Simple remote.
To use the Roku Express with the Simple Remote, just press the Home button when you are ready to start streaming (wakes Roku device), and then press the Home button again when you are finished streaming to return to Home Screen (stops data usage and device will eventually enter sleep mode).

Currently, the Express 4k+ (3941) is on sale for $30, which is what the new dual-band Express HD (3960) is currently selling at. You will normally find the same price at retailers (Walmart, Best Buy, Target) to be offering at same price as Roku website. This device will come with a Voice Remote with TV controls and is certainly an upgrade over the basic HD Express. (the 4k+ will stream up to 4k resolution. Will work on both 4k and non-4k televisions/HD).
If you can, may be worthwhile to return the current HD Express and purchase the Express 4k+.
