Review on Waterproof Strap-On Saddle Bag for Bicycle: TecTri Bike Seat Pack with LED Taillight & Mesh Pocket by Jason Gopinath

Very easy to install. a bit smaller than i expected but enough for my iphone, keys. It tapers towards the bike, making it difficult to fit everything. But overall I like the bag and it was easy to install. The light that comes from it is useless. I couldn't remove the cover to put the batteries in, so I just used my old flashlight. It seems very durable, says it's waterproof but haven't used it in wet weather yet! My husband was able to remove the cap from the lantern. It doesn't slip like someone said. He jumps out. Therefore I give 4.5 instead of 4 stars! Guess I'll have to keep my husband now if I ever need to change batteries!
