As for me it is durable as I am using it as a night lamp and been removing and putting it back on for a couple of months already from and to the lamp. I know it is not a good practice but I do not have the designated lamp for the red light bulb yet.
That is true. Actually, I’m using a different device before. But, after a few weeks of using it I never get the result that I want and it is also irritating to my skin. At first, I just tried to use this rubylux and I ended up using it for a long time now, Since it’s working for me pretty well.
