My local pinch a penny is now selling this solely. Anyone used it? Same as regular MA?

My gut says it's nothing but half strength MA. That jives with the reduced fuming, and generally 15% MA etches roughly the same as 30% MA so their claim that it still works for that would be accurate.

However, they say it's a proprietary formula and I cannot find an SDS for it. Without that I'd personally find a new source of MA that I can verify doesn't have any secret ingredients.
 
I like the fear mongering of not being severely burned. I've been splashed / dropped many times with full strength MA and with the pool *right there* to rinse my arm or whatever I finish the job, then walk *right past* a hose to the driveway to throw out the jug, then go inside to wash with soap. I might even check the mailbox between the garbage can and going to wash off.

Everybody's skin sensitivity is different of course, but still. It's nothing like it's made out to be. It needs to be respected but not feared. Fear causes mishandling or inattentiveness which then creates problems that didnt need to be.

I also like their 'Vapor Reducing Technology (VRT)'. In some parts of the world they call it 'adding water'

I mistakenly ended up with a gallon of this stuff from my local Pinch a Penny here in Texas. It was on the counter and the cashier had rang it up before I noticed it wasn't the usual Champion brand acid I get there. Upon questioning, they assured me it was "just as good as the other stuff", but I was immediately skeptical since I could not find an actual strength % listed on the bottle, which was a huge red flag.

After using up most of the bottle, I can confirm this stuff is definitely not full strength and does not have the same impact on my pool's pH as every other full strength 31.45% acid I've ever used. I'm having to use about twice as much to get the same effect. Wasted money. I won't be buying that stuff again.

I'm surprised they'd just swap one product for another like that, because it will absolutely have an impact on their customers' pool chemistry, and not for the better. I noticed "Suncoast" on the label (visible in photo in first post), and that seems to be their in-house brand, so my guess is they are just switching to their own in-house brand acid.

Yeah, the guy at my store claims it was a supplier issue but you are probably correct. I returned mine for a full refund as I suspected it was diluted per the discussion here.
