Trolley Collision/Momentum

We will need new ones next year, just had a look, so many on the market now. Perhaps the chemtalk family, would mind letting me know which ones you use, have you had any problems??

I replaced our old ones with the red "hyper fire carts" made by IEC over 10 years ago. They have lasted very well. Of course they were expensive even then - about $50 each, but bought 2 each year, till we had 10.

Where did you buy them, please

We bought some from Serrata about 2 years ago. They were $120 a pair. Good luck with them.
