I have used it two times. More than 10 years ago I tested some useless low-end analog models Wired and wireless sound reproduction are not the same Good value for money. I read reviews on the site stated above before buying this product. Given that stand-by time is questionable, I also bought on ebay an external 5500mA USB battery the size of an iPhone for less than $25, and therefore have no problems with battery life. Receiver/transmitter recognition is very simple. I started the test with a distortion sound (gear used: fender deluxe strat plus, Pod xt live (both connected wireless, pod connected to a marshall valvestate wired between the line 6's line out and the amp's guitar input). I immediately noticed that there seems to be some sort of noise gate, as if missing part of the first note, the distortion proves to be a bit less warm or maybe it's just the signal that is weaker. I then tried with a crunch sound, which lacked attack. In spite of all of this, it's not bad, but the sound is different when using cables and basic settings. I added some saturation, presence and volume to all my presets to get the same sound I get with cables. As a consequence, I saved my presets for "wired" mode, just in case, and also other banks for wireless use.</div>
