ABUS Coil Cable Lock

I have a discover 1 and I love it! I use it to commute to work 5 miles each way and also for fun. ,grocery store,going anywhere I need. So securities very important to me as I park my bike outside all the time. Except when I'm home. I currently am using a lock that looks just like this one I got for $19.99 and I bought another thick chain lock for $30.00 both have keys. My next purchase will be a tracker for my bike since I have an android phone being thatthe discover 1 is not compatible with your built in find my bike apps basically I will be able to have all 3 security measures for about the same price as this lock!! Am I missing something? Please explain why this is priced at $69.99 I gave 4 stars for my bike not the lock. Thank you velotric
