I liked the original too, the long soft pull click on and off was great, just like a bathroom light pull cord. However the shafts broke on mine as they were so over used, but i still have a couple of spares for it i think, if anyone needs any in the future.
I changed over to the univalve afterwards and got used to it eventually, but the more flexible your pole hose is the more it absorbs the "pull" especially in the summer. So at full pole extension you can be pulling several times before it turns it off, i remember doing this whilst cursing the bstrd, only to notice the customer watching me from one of the windows. I hate it when that happens!
