Post:

Hi Richard,
In my experience, they are equally durable. The metal carts have plastic end caps that break when dropped, and the impulse of the dropped cart is greater since it has twice the mass. The durability issue seems to come from the plastic plunger, which wears realatively quickly so it does not latch after a year or two. The "go-car," which has no plunger is a great deal though.

Hi Tappers,
Do any of you have both types of pasco carts (metal and plastic) and can
comment on the relative durability of each (or other comparative
issues)? I would like the plastic carts because they weigh less and
thus you can change their mass by a larger percentage with added
weights. But apparently our local pasco rep advised us against getting
them because they were not durable enough or something (I'm getting that
info second hand).

Thanks,
Richard
