Does anyone have any experience with Markerstudy? A-Plan seem to use them for their insurance offers. Elsewhere on the web I came across pretty bad reviews on their service etc.
They take a while to pay out (several months in my case) if you need to claim, and they can be forgetful. They seemed just like any other underwriter really - they paid out for me in the end.
Other than that, they were happy to provide decent price cover for me for several years.
