Yes and No,
I personally think the xAC is a great product, great price and the antenna is excellent for xSeries implants.
The Mod That @Devilclarke is working on ( Toggleator ) is a very elegant and simple add on solution.
Also I believe his longer term plan? is to possibly / maybe come up with an all encompassing design in conjunction with DT and I assume @TomHarkness for antenna design?
