Not a gamble at all - I was planning to add this ON TOP of insurance! It's fine having your bike insured, but if it gets pinched and you can get it back, because you know where it is - it's your bike, I assume you chose it because you liked it, so you want that bike back, not necessarily a new one! If the insurance pays up and you are still able to recover the bike and buy it back off the insurers, even better!I don't but had a look on eBay and if you type in 'gps tracker ' there are lots for not much money. Bit of a gamble, I'd go for insurance too.
