Meg-mo knives instead of blades

Does anyone have the Meg-Mo "knives" on their equipment? If you read their site (www.meg-mo.com), it sounds like the best thing since sliced bread, but you know how advertising is.

 

They sound pretty steep to me. I understood that the prices were per spindle. I have 3 on each mower. That could get expensive.

 

Do a search there have been a few threads about them lately.

 

I had some on my mower for a while. They didn't quite work as good as promised. But some people think they work well. My biggest complaint was blow-out's and packing the deck with wet grass.

 

At this point (grass is wet in spring around here), I wouldn't expect them to be any big shakes. I was more interested in how they perform during summer, when things around here are a bit more arid.

 

We just strarted using them today and they do a great job on mulching up the grass, I hope they continue to work well.

 

I wonder if they make the mower have the same sound as normal highlift blades?
