I play in a trio (with a few guitars between the two of us), and even with such a small group we had a tangle of black cables everywhere. Both us and the audience didn't appreciate this mess and we were constantly tripping over them.
I bought these X-Vives and they are brilliant. Just plug and play. What a joy to now have clear floor space and complete liberty to move around !!
Super easy to operate, discreet, good range and has a very reasonable battery life. At this price you get an amazing bang for your buck. Four channels available which - if managed properly - should suit most amateur set-ups. Some people test these things to extreme distances (and they still work well), but for 95% of players standing a couple of meters in front of their amp and playing in a small to medium café/bar/club, you will have no problems.
I took off one star since the battery can't be replaced when it wears out, but hey at this price I can buy replacements without fretting about my bank account.
Thoroughly recommended. You'll wonder why you didn't do it earlier.
