Thank you for your input on this, I want you to know that we have people in these forums so we can gather everyone's feedback and understand where the market wants us to go. We will of course consider bringing something like the Masterspool back in the future but for the moment we will likely not do so. One of the main reasons is that in theory it is a great product with a number of people making it known that it is a great idea. However when the Masterspool came to market it was an option that not many people tried and fewer returned to.
We did actually market the Masterspool fairly often and even before I joined Matterhackers I had seen numerous twitter posts and email blasts about it. Those attempts mostly fell were met with silence and the spools did not move. Unfortunately it seems that this is one of those projects that everyone agrees would be cool but once it comes around no one wants to take the time to use it.
In the future we may be able to carry a spool that fits the same requirements as before but for the moment we are going to take a break from it and continue to track what the market wants.
