I had some bubble liquid that was really good sadly its all gone, so bought some Skytronic "High Quality" but it's rubbish - it's just too watery - more of it is spit out onto the floor and just makes it slippy rather than it making bubbles I did think it could have been a one off, but the thing is I bought it from terralec who didn't have any in-stock, so at the same time I got some from Djstore.com both lots are the same - waste of money
I've ordered some ANTARI CONCENTRATE so will see if thats any better. It was a bit pricey though - but would sooner pay more and get proper bubbles so hoping it works. I've had some concentrated stuff once before from terralec and as far as I can remember it was OK, but can't remember what make it was.
If you have any other suggestions let me know. Cheers.
