I use one in my dirtbike since I change so frequently with it, i felt it was worth the cost to get one, believe it was around $60 for it. For my streetbike at the time I believe it was around $120 or maybe a little less, but I decided not to go that route.
is easy to clean, i just use simple green and hot water or soapy water and rinse off let it dry, put back in. no issues with it in the couple of years I have been using it.
I have about 12 Pure one PL14610's that I got at amazon when they had two for one for $5.88 so i snatched up a bunch for the bike and corolla.
