The paint rollers that hold paint in the handle?

Are they worth the money? I need to paint my celings but am getting on in years, do they work well?The paint rollers that hold paint in the handle?
I had one and used it once. If you are really strong you might like it but I thought it was heavier and more difficult to use. You do save time not putting the roller into the paint tray all the time. I would rather just put an extension handle on a regular roller.The paint rollers that hold paint in the handle?
They work great for large areas, but for small areas I would use a regular roller. It takes so much time to clean, it not worth the bother.
