Convenient but subject signal interruption

The (+):
Small, easy to connect, received signal has approx. 4m in my case,
its qualitatively correct, quantitatively also subject having "Watts reserve" on the chain (it takes up the volume)
small halo (unlike some models seemingly more "discos" ...)
relatively simple pairing (it's a problematic side PC / OS all ways)
well what to book with and without excess packaging instructions.

The (-) directly inherent in homespot and technology (Bluetooth):
Signal easily ax, even without passage through the field between the PC and the receiver (?!)
sometimes total loss of the link or obligation to re-pair,
cables (audio and alim) a short hair.

The (-) potentially related to the PC (Acer core i5 8GB RAM running Win8):
Immediate loss of the link observed particularly but not only has the opportunity of connecting a USB peripheral (non-musical) to the PC being read-emission homespot to (it makes clear: "And I cut the sound ..! ")
randomness of setting has available (handy) of the volume control and more dedicated sound homespot speaker volume PC (frustration of not always have both)

IN SUMMARY,
good performance for the price, did the job once "spear" but seems to require to have the perfect sight line receiver to the PC without a chair back edge early or cat stealth passage between the two ...
