When I visited Ironsure.com and got a quote I thought I was on to a real winner, but I read the small print luckily (I think).
I'm not a gambler so am not going to say it's a rip off because I haven't tried it.
Their quote was very cheap, but it is a monthly renewable policy meaning your payments can go up or down each month.
Ideal if you need short term insurance without a commitment, but long term youd have to check it out each month.
Could be a good idea who knows, just shows about the small print.
Maybe the company could offer fixed insurance as well as variable a possibility for the future. If your brave enough to use them let me know if it's a good deal please.
