Hey Scott,
We greatly appreciate your feedback. We always aim to provide high-quality products that will last for plenty of riding, so we are dissapointed to hear that this was your experience. We don't often hear of bottles dislodging so please see below for some technical assistance and tips!
Our washers are meant to provide support for bike configurations that require the use of shallow screws. For most bikes, the washers are optional and may cause your Bike Base to become loose if not needed. Unfortunately, we don't offer the washers for sale, but often offer them upon request for warranties.
Loose Bike Base screws or an upside down configuration are often the cause for dislodged bottles. Double check to make sure that your Bike Base is facing the correct direction (tail-down) and your screws are flush with Bike Base.
We apologize for the inconvenience that this experience has caused. Please feel free to reach out to support@fidlock.us to request a warranty shipment; we would be more than happy to help!
