The Good
Super convenient
The Bad
Requires prepackaged transfer packs to take full advantage of convenience
The Bottom Line
This is a great product. Using the prepackaged transfer packs, a satisfactory transfer can be completed in a few minutes. It is of course more expensive than a traditional wet tank transfer. Considering not only the speed but how much general hassle you avoid in buffer preparation, membrane and filter paper preparation, material equilibration, equipment washing, etc., I believe this workflow is well worth it. Unless you have a special reason for running wet tank like highly optimized buffer and run conditions, this is the way to go.
