I've got the tailpack. It's been on my bike pretty much constantly since I passed my test 7000 miles ago. I use it to carry my lunch and normal trousers to work. It does the job. I lost the rain cover early on, somewhere on the 75-mile journey to my parents'. I lost one of the bungees and I replaced it with some shorter ones because most of the time it's not very full. At first I thought the bungees were a faff (the instructions say you must use them, they don't show them on the photos, funny eh) but I've got used to using them. They've put a few scratches on the bike though. The zip pull on the rear pocket is like a normal zip pull dipped in rubber to make it bigger and the rubber bit has nearly torn off. I hope I can attach a bit of cord (or insulated solid core wire, my usual zip pull fix) so it remains easy to open. It's not a luxury item but it does the job for not too much money. I've also got a tank bag (Buffalo) but I only use it on weekends away when I need extra storage or if carrying a pillion. I prefer the tailpack as it is out of the way behind me.
