How well do reality checks work for you guys?

I personally do not do any reality checks to lucid dream. I have done them a few times though in a dream and have become lucid though. My main thing with reality checks is a lot of them assume you are in your dream body. I have had many dreams where I have no body, and I am simply observing a scene or scenario and so something like counting my fingers would render ineffective for my lucidity.

I'm curious to know how well they work for you all, and if you guys have other methods that work better to help you guys lucid dream. If reality checks do work for ya'll, which ones are the most effective?
