Many of us love them, but some don't. They usually require a little tweaking and diddling out of the box to run their best. If you liked old Aurora Thunderjets and you enjoyed tuning them and tinkering with them, you'll probably like the JLs. It's been said that the quality control on the JLs isn't as tight as the old Auroras, and that seems to be true, but that doesn't mean they're not fun...
Be aware that to get the most out of these cars, you might eventually want to invest in a couple of controllers that are a step up in quality from the ones that come in standard slot car sets. The standard controllers are going to seem like "on-off" switches... either you're going too fast for the next curve or you're stopped. A higher-ohm controller (they're probably about $35-$40 each between the Parma controller and the custom high-ohm resistor) makes them much more controllable and fun to drive.
Just my 2 cents, I'm sure others will chime in with opinions...
