Any thing that has moving parts is more likely to fail than something with no moving parts.
It could be that supporting the Rat Trap was too much work, it could have been too time consuming to build or they took it off the market so the Busse folder won't have to compete with it.
Who knows?
Other buisnesses will sell some items at a loss just to have a complete product line but how often does a Busse company act like another buisness?
