These ramps are great. They’re pretty heavy but perfect for non-slip placement. I’ve seen some complaints that they could be more durable, it seems as if the plexiglass was a little soft but I can only disagree. I actually found them to be one of the best ramps for practically anything.
Not many companies produce plexiglass ramps. One of the best is probably -inexp fingerboards-. They come in practically any shape/form and are usually more unique than regular wooden ramps. Here is of one of my favorite models:
The inexp wave (made in France, 34cm by 6cm by 5cm). The unique shape and superb quality reflects the time used in the making of this ramp. Definetly worth to try out and to include in your daily fingerboard run 😉
All in all, the plexiglass ramps seem to have great potential. I find them to be great for all tricks (especially grinds of cource).
