I posted about this a week or so ago, and someone asked that I let
them know I feel the sprays when I had a chance to try them.  They came
in the mail Thursday, so here is my reviews of things.  I tried four
flavors; marshmallow, buttery, teriyaki, and ranch.  The Burke's website
is at http://www.flavorspraydiet.com/ .  I am not employed by or have
connections to chef Burke, this is just my take on this products that
I've tried.

This the "flavor spray" meal I had Friday night.

5 ounces frozen green peas, cooked plain in microwave, no water or salt
added.
Divided into 2 piles on plate, 1 portion sprayed with 2 sprays butter
flavor, other sprayed
with 2 sprays ranch

butter-- not very noticeable, not much smell.  Little if any salt taste.
1 spray on finger, light but artificial buttery flavor (no surprise
there), moderate salt. Light intensity

ranch-- some herbal and dairy notes, very faint, but definitely
different than plain peas.  
Very light salt.  Smelled like ranch dressing. medium strong intensity
1 spray on finger, medium salt, surprisingly sour, though not
unpleasant. Some "ranch" flavor.

1 6 oz tilapia fillet, cooked in cast iron pan w/approx 1 tsp. crisco,
no seasonings added.
Plated, then sprayed with 4 sprays teriyaki flavor.

4 sprays... couldn't taste
1 spray on finger to sample, pleasantly sweet and balanced teriyaki
flavor, med-light intensity
4 more sprays on fish, light, pleasant teriyaki, very nice flavor

Marshmallow
1 spray on finger. sweet, defiantly "marshmallow", medium intensity,
strong marshmallow smell
2 sprays onto approx. 3 ounces of fat free cottage cheese-- Definite
marshmallow smell.  Very light, sweetened tasted.  

 Conclusions:  I should point out that I have sinus problems, I tend to
be pretty bad at tasting subtle flavors.  The bottles and website
recommend 1 or 2 sprays to flavor foods, but for me that simply wasn't
enough.  The fact that I didn't salt my food beforehand might also be a
factor, the sprays were going onto some pretty bland foods that demanded
a fair amount of seasonings.  I think that the flavors of the sprays
might be more pronounced if the food is preseaoned with a reasonable
amount of salt.   All in all the sprays taste good, in particular the
teriyaki flavor.  But I had to use alot more than recommended to get
enough flavor to be able to enjoy it.

  But even so, I think it might be worth it.  The chef claims there are
about 400 sprays worth of product in each bottle, and I have no reason
to disbelieve that.  Even accounting that it takes 8 sprays to flavor 6
ounces of fish, that comes to 50 servings per bottle.  With shipping,
each bottle comes to about 6 or 7 dollars.  That doesn't seem like an
outrageous price to pay, to me.  It is very easy to use, has a nice
flavor, and does save some calories over the more traditional sauce (I
had been using Kikkoman's Teriyaki Baste&Glaze, which claims 50 calories
per 2 tablespoon serving).

  These sprays might not be to everyone's liking, but I think that I
will by buying them again, especially the Teriyaki, and I am tempted to
try some of his other savory flavors as well (I'm just not as into the
sweet stuff, not because I was overly disappointed with the
marshmallow).
