I have also used hot glues.
There are several consistencies available.

If the areas are perfectly flat, tape works well and is reversible.

Silicone glue is my favourite, but is difficult to remove.
Hot glue is more easily removed when needed, but does not adhere as well as silicone.
Glues are good for non flat areas such as soldered pads, terminals, switch leads etc.
