So I've done some more research, and found that the reason the I-Boss is so cheap is that they were able to change some stuff in the manufacturing process which made it considerably cheaper while still providing the exact same product. The reason for this might be that they moved on to produce the mini, and more. Further more, the IT itself is made of Kevlar, and most people are recommending it for people new to ITRs because I am less likely to break it while practicing (it is a lot stronger and thicker, but still pretty much invisible). So it's cheaper not because of the quality, but because of the manufacturer.
That being said, I might take this one to experiment with before eventually buying a top end one (T2, Venom, Spider Pen Pro... any others? Also, any major differences in the 3?) whilst still experimenting with Loops (I am breaking them way to easily).
