There is a local guy who used to use something like that and a Yamaha drum machine as a solo act. He did hundreds of gigs as a full time performer back in the 80's. Later and to this day he uses a bass player. I backed him a few times and he didn't like it when I walked a bass line. " Root five" he would yell at me! He was so used to his plodding bass lines.

Bit pricey.

Curious how it can "Control your DAW up to 100 feet away." when Bluetooth only goes 30ft.

$300 and it's made out of Plastic? Myself wireless is to be avoided when the word "bulletproof"  is involved. 

Not all Bluetooth is the same.

Class 1 Bluetooth has a range of up to 100 metres (330 feet).

The device in your link is claimed to be Bluetooth 4 LE. The maximum range depends on the devices concerned, but the Bluetooth SIG suggests Bluetooth 4 should have a range of at least 200 feet.

Thanks, didn't know that. Looks like it depends on TX's power level/antenna length. Most mobile/battery powered devices are probably class 2.
 
Class 1 = <30ft
Class 2 = 30-33ft
Class 3 = 328ft to 1 mile (modded)

After several years, I still see that the only affordable multi-purpose foot controller is FCB1010...
 

I too use the FCB1010 - have two of them.  $140 new and built like a tank.  Can send up to 5 midi messages with 1 press.

Just a follow up to this. So far the Stealth has performed flawlessly after a dozen gigs with it. 
The best part is it's not fussy about which computer  or USB port used. Just always works.
