Review on 🔌 Wiha 61620 MaxiFlex Outside Extension by Derick Johns

Excellent range. The locking is more precise than wood as it locks firmly at 90 degree angles. It's totally waterproof so it will last quite a long time. The sliding scale is a little loose for the first few inches, but quickly tightens to keep it from falling out entirely - looks like it should. This is a very high quality meter that certainly gives the impression of being made in Switzerland. I swear by folding rules these days and find them much more useful than tape measures. It's also less flexible than a wooden ruler without feeling brittle or weak. This makes checking much easier if you keep it in the right position for the measurement.
