Auralex Acoustics Lenrd Bass Traps Purple

I use these 'Auralex Bass Traps' in my 'Recording room in my Home-studio ' ..
Pros ;
They 'just simply , make the biggest difference in sound quality ' , it's like 'Magic' .. Unwanted rumbles just disappear .....
cons;
I got none , bar maybe ? ( but not really :) .... having to make my own stands for them :) ..
But , isn't that half the fun, when getting a bargain , with no frills or thrills .. & I guess , that is why they are so 'Low in price ; relatively speaking in comparison to others ..'
These are the 2nd/Complimentary set of 'Bass Traps' , that I utilise in my 'Recording Room' & if I needed more ? i.e. 'in the Mixing Room' ?
I would definitely be 'buying Auralex again' ..... 'Loud Drum Sets & even 'Live band scenario' , are now welcome .. :) :)
