why would anyone want to use any other design than this?
no need for that installer, and u can do emergency repairs fast and on the go without any tools at all. The long straight ones may be more versatile, but they need wirecutters and careful technique not to slash up the euph's finish. my euph was resprung with one of the those and 2 of the traditional long ones. because they had to be cut, the 2 that I took out to install my new waterkey need to be thrown out. ....if only i had 2 more of those from the link
