I've had another brand of trekking poles for a while and one of the lower sections broke. These poles looked similar so I talked to someone at Hiker Hunger. Not only was the rep super friendly and helpful (despite my poles being from a totally different Co. I couldn't find), but they also took got back with measurements to see if they'd fit, and then followed up. Turned out that the diameter is more like 0.510 inches (and not 0.5), so they didn't fit in my old poles. But I liked how sturdy and well made the sections looked, so I just kept the sections for spares bc I bought a whole new set of carbon fiber poles from Hiker Hunger (^‿^).
The poles are really well built. But it's the little extra bits that go a long way, such as good rugged metal flip locks, strong webbing straps with padding, and raised rings near the carbide points to help keep the rubber rock tips on when using those.
One point of improvement: on the middle section, I'd like to have the adjustment marks every inch instead of every two inches.
Suggestion: It would be nice to have a threaded sleeve without a basket if someone wants to avoid baskets getting hung up on brambles but also wants to protect the basket threads on the poles (yeah, I'm pretty hard on my trekking poles (≧∀≦).
So far, I'm pleased with the build of the sections, enjoying the poles plenty, and SUPER happy with the customer service. A good company I'll be recommending in the future too.
