@maitland88 I claimed with Urban Jungle and had 0 issues. One phone call, emailed over some documents and then a final phone call to confirm. They had no issue with the replacement devices I bought even though they were slightly more expensive than the ones that were stolen and my premium only went up £4 a month. Whole thing took just over a couple weeks.
