Pre-gued tyres?

[chris68nufc]

What is the general opinion of the pre-glued tyres? I personally think that they are a great idea. Very easy and no mess.Buy them, run them and buy some more when they are shot. I have been recently using acetone to re-use some of my older rims and also the same foams that are fine to re-use and cant make up my mind if i will fancy using the new pre-glued tyres.
What do you think?
