Fun Generation AirZone 5.8Ghz Instrument

In the past, I've tried lightweight, inexpensive transceivers belonging to friends and been very much unsatisfied. I've also long had a love/hate relationship with wireless - the freedom is wonderful, but the sound and performance infuriating.
But, for this price, worth at least having a go, I thought.

The short answer - fantastic. Reasonably fast charge, a good three hours or more continuous use (fine for gigging), faultless transmission, and sound quality equal to a cable.
I can say this, as I did a test sending white noise from a synthesiser simultaneously via a short balanced-line cable connection, and via the wireless. Using a Match EQ program to show up any differences, it revealed only a slight roll-off (around 0.5dB) below about 50Hz, and the same at the high end, about 18kHz. That's virtually undetectable through guitar amplification - and better than the response of any unbalanced cable over about 2m. Fab.
Despite what some misinformed reviewers have said, there is no detectable latency; probably those folks were confusing latency with the difference between the speed of light and the speed of sound. :)

Impressive enough and ridiculous for the price, so I bought a second (for the piezo out from a couple of my guitars).

Without mentioning any names, a few years ago I bought from Thomann a bug-and-floorpedal set from an internationally famous audio manufacturer. That takes 3 hours to charge, plays for about 2 hours, the bug failed within 6 months (Thomann replaced it) and within another 6 months, the replacement failed. Same problem - poor design of the "swinging" jack in the surprisingly cheapo bug. I've subsequently repaired that a couple of times myself, including also curing the battery charge monitor calibration. On the plus side, the tuner floor receiver is paradoxically bombproof. But that cost me over 300GBP!

The only drawback with this fantastic value wireless kit is the silly name "Fun Generation". If you're wavering, buy one.

I bought these as a spare set in case my Mooer set went flat during a gig. I have used them in rehearsal with no problems. I am primarily a bass guitarist, but have used them for 6 strings too. Having the channel display on both transmitter and receiver is really nice, and they pair really quickly, and so far reliably. The rotating plug is firm enough and the transmitter stays at the angle it is set to in the guitar jack socket. They are clearly made down to a price, but they work and don't feel as low cost as they are. I may update this review as time goes by and I use them more, but at the moment I have no complaints. I am tempted to get a second set.
Updated: battery life is still very good. We play a 3 hour set and they are still going strong at the end of that. I have had no drop out or sound quality issues with them at all. I have the receiver plugged into my multi effects unit on the floor - the range is about 25m used this way. Because they are 5ghz interference is a non issue.
A word of caution - the transmitter cannot be used with an Ibanez Bass, the reach between the body is insufficient.

Works perfectly fine...in your bedroom. After a single gig, here are the cons...
1. Battery life is NOT 8 hours as advertised. Closer to 3/4 hours. I did leave it fully charged but unused for a week though.
2. Apprx 5 mins of low battery warning is too less to be really practical.
3. Smallest of obstructions caused signal drop. In my case, it was some tables/desks that didnt even have the lower part fully covered.
4. Usable distance is around 35 metres as advertised (I wish this advertisement was being on the safe side).
Most appropriate use of this gadget would be in practice or on a stage which one is already familiar with. Its ergonomic, looks good, dual charging cable is a plus, no signal interference (5.8 ghz helps), and most importantly there is no noticeable latency or tone change.
