I have this glide john bit I dont like using it are the green glides better
its hard to say what you've got there from the picture , iv only experienced three glides , the ones cleansmart sells are real greenglides , they are quite heavy like a policemans baton , on the other hand i got an unknown brand one from woodbridge ( worldwidecleaning ) and its quite a light square glide thats not near as good .
The glide that came on my dangpro from the states is also a really substantial thing .
Any of them might not be for everyone , so use what you feel gives you the best ease of use /performance .
The Greenglide i got ... i drilled holes across the slots in order to pick up pick up fluff better and i think gives me better airflow , would not be sure of that though .
