Been doing some sample quotes on Go Compare and Devitt are coming up a couple of hundred cheaper than everyone else.
i had a bad experience with them… wouldnt touch them again. I had to involve the financial services ombudsman before they were willing to sort it out. 
I had insurance with them on something or other, never claimed though so “it’s a piece of paper that means you can tax it and don’t get pulled by ANPR cars” is about all I can say about it.
i`m with them. they seem pretty efficient and are cheap. never claimed from them so dont know how that goes.
Bad experience here too, wouldn’t touch them with a bargepole, ended up in court against them, sorted in my favour thankfully. 
had a policy with them, cancelled within the 14 days and switched to carole nash.
devitt customer service are 0/10
Accident I had when with them, took a year to sort out, I had to chase them, they never did anything to help me or offer me advice even though I paid extra for legal assistance and eventually had to settle for 50/50 liability even though the guy did u-turn in front of me. Landed up getting nothing back in the end because I wasnt fully comp 
Food for thought…
Thanks.
I seem to be going against the grain …
My cg was stolen in under 2 weeks of having it and they were great, processed it quickly, kept me informed and ended up paying more than the bike was worth to fix it and give it back to me!
couldn’t fault them…
