The belt buckle on my Sitka dump truck broke so I tried the Cobra. The Cobra is a great buckle replacement, fits perfectly, holds tight and opens smoothly. I wasn't impressed with Sitka, but so far the Cobra buckle outperforms the OEM buckle. Chased at high altitudes in the snow and cold rain/sleet, the buckle was firm and easy to release. It is very easy to recommend this product.
