I had some problems with the Fat Daddy 510 as it always leaked a little and as it was spring loaded I also had some connection issues. There is a different version available now so this might not be a problem any more.
The keystone battery sled was also prone to tearing battery wraps.
Getting everything to fit in the enclosures available is more time consuming and awkward than you might think. You either end up with a large enclosure or having to modify the enclosure and the other components to fit.
I looked at having my own design of enclosure made at a local machine shop but the cost was prohibitive, especially as I was unlikely to get everything right first time.
Unless you really want to build your own
mod and have access to the a milling machine etc then its much easier to buy something off the shelf.
