The TWS 16 PT is a cheapy, simply and good working wireless system. 
It bridges long distances (around 60m) and the working-time with one pair Batteries is really long (I change them once a quarter year, weakly playing)! 
 
The top side of the receiver is really delicate against scratches. Two weeks transporting the Box in a Bag with cables and other Equipment has been enough to make the receiver look bad. 
Later I had problems with the antenna: 
The screw that fixes the antenna at the circuit Board was loose- You can repair this easily by opening the Case and bolt down. 
 
These problems are okay for this price but it really disturbes me that you can not find a good Mini-XLR Cable for transmitter to Guitar. The included cable is bad standard-ware and keeps no long times. 
Furthermore it isn´t angulated and thats really useful cause it looks better and also protects the guitar connecting socket against quarrying out. 
 
Finally I took a TQG-Cable from shure (It costs 30€ :( !!!) and brazed the cables to mini-xlr.
