Sorry for our tardiness and thank you for the heads up.
We have investigated the details of your case and I have arrange the paperwork for a credit for the out of stock bi-pod and partial credit for the fan less mask as they are still somewhat usable.
The RMA number is still valid for the chrono and I'm sorry will need to be returned for inspection and replacement.
I highly recommend the Xcortech X3200 model as we use this model daily and haven't receive any complaint or fault for this model. Also it use AA batteries making it most handy.

Again I'm very sorry for the delays in these matters and hope we can sort them swiftly.
