I have only used this for a couple of hours but so far I'm pretty happy with the purchase. I bought this to go on my Mustang 310 skid loader to help with moving compacted soil around. It's a pretty small loader, so having the extra bite really makes a difference. One thing, make sure you measure your bucket closely before buying. I read other reviews stating they had to grind the ends down a bit, which i was OK with. My bucket had welds right where the tooth bar would slide in, so I ground the ends and tried to fit it. However, i didn't realize that the bucket had a 7/8" thick by 4" cross-bar welded onto the bottom about 1/2" back from the cutting edge. This made the overall thickness about 1 1/4" and i wasn't able to slide the teeth over the edge. Since i already modified the bar, i figured i'm past returning it so i ended up cutting the bottom of the teeth off to allow just the front of the cutting edge to slide in. I was a bit worried about how this would hold up, but it didn't budge even with aggressive digging and back scraping in tough compacted soil.
