If you're only in Tenerife for vacation, don't go there. Even if you have seen everything, it still feels like a waste of time. Besides, the majority of the information there is displayed only in Spanish even if it seems that only the tourists visit it.
The museum feels forgotten and outdated, full of light-bleached pictures, old non-working TVs and walls of text. Moreover, in places the text has low contrast which makes it hard to read.
The building has 3 floors. We spend around 2 hours there and saw most of the expositions. There is very little interactivity so going through the museum can feel quite boring and tedious. It's a shame because there are many interesting expositions that with a little update and more cohesive layout could make this museum a lot more enjoyable.
Only time to go there is from 4 PM on Fridays and Saturdays when the visits are FREE. Don't try going earlier because they'll make you wait until it's 16:00.
