Matthew Pizzawrote a review of Timbuk2 Tandem Pannier on May 31, 2016
Familiarity: I've used it several times
These panniers are great for the average commute. My 15in laptop fits in here no problem, along with a change of clothes, shoes, lunch, and whatever else I think I might need for the day. Much easier to ride a bike with all your gear not on your back.
The pockets/organization is really well thought out as is the case with any Timbuk2 product that I have ever owned. Waterproof material and large overlap of the lid ensure that your gear doesn't get wet if you get caught in a storm.
These are my first panniers and they are great. I would however like some that have a little more reliable rack attachment than the velcro that is on here. I had a mishap where the velcro came undone and the pannier flew into my spokes and now has a big hole in the bottom.
