Really liked the idea of 8 mics using one receiver box. Thats just so great. I think this system is great for most amateur and semi pro applications. I have worked with Sehnheiser wireless for a number of years. Lets face it. They are great but at 700 bucks for one mic and receiver thats a big investment for something you'll never make up. After the initial use of this Nady system I think I'm happy about getting it. I bought it to use with my Tri amped PA for a small band but used it today at church. I had 4 of the mics running against 4 Senheisers at the same time. I had a bunch of young ladies about 150 feet away singing along with a piano. The pianist used her Nady to narrate without incident. It definitely sets up eq and trim wise different than the Sehnheiser. With all the singing I couldn't tell much difference. Hadn't tried it for a soloist yet. The mic is pretty bassy up close and can pop some. Maybe a foam will be needed. Don't know yet. I think these would well for a band, including miking instruments and amps. I haven't tried the line out yet where its a summed output of the 8 mics. That might prove handy in some appications.

Sound
Solid. Similar to SM58 or better. Eq some low end thump out.

Features
Most useful is all of it. I like the rack mount option that comes with it. They included alternate way of mounting antennas. On off on mic is handy. Least handy is: managing 8 wireless… read more mics can be tricky so i use colored tape. Difficult here because of location of on switch and battery compartment.

Ease of Use
Easy to set up and use. Trims well. I did not have alot of fb problems.

Quality
Made very well. Mics are light compared to SH. Looks nice. As nice as SH without frills.

Value
I think its a bargain.

Manufacturer Support
Nope

The Wow Factor
Looks simple but elegant. Receiver looks nice in my rack. I like the fact you have balanced mic outputs (xlr)
