This is our second year with one and I can't find anything bad to say about it. Gleaner is impressed enough with them to sell them through their parts system and my guess is it's just a matter of time before they are an OEM option on most new heads. They might have a slighly higher maintance cost than a regular reel but all they are is a roller running inside a plastic track and from what I've seen on our's I'd expect at least 5,000 acres out of one before they are going to need anything replaced.
