Like it, good product!

As advertised, packaged well and delivered promptly. Likely ordering more soon

This means all the fibers run parallel to the shaft. Shafts are extreme strong in tension, which is what we wanted. But a warning though: it splits relatively easily along its length. (think of how wood splits) The listing mentions something like this. It shouldn't be a surprise. Worth mentioning again though.

Good product, popular, and priced right
