This is a nice item the only fault I had which might be the way i placed the disc is that the disc gets a little wet as the edges arnt water tight, it does have a sealing ring but the whole thing isnt bug enough to surround the disc unless you trim it to fit. All info is clear to see through the window so does the job.
