I really like my orange HF battery grease gun. I had to use a pump grease gun when I was a kid way more than any person should in a lifetime so anything that can help greasing is good. So far it is holding up well with good pressure. I think the batteries for these are better than their 12 volt cordless drills HF sells. I put a Lincoln tip on it after I ruined the stock one on a broken zerk. I bought the HF pneumatic grease gun several years ago but it wasn't worth a crap so I returned it.
I used the 4 1/2 inch grinder with a diamond blade to help
cut the granite I installed in the kitchen and bathrooms and fireplace hearth on the house I built. Still going strong. I am proud of the way the granite turned out.
I also used the 7 inch polisher to shape and polish bullnose and top polish joints on the granite. It is also still going strong. I used diamond polishing pads from a stone working supply store.
The 10 inch "Industrial" tile saw impressed me. I put a lot of tile in the new house on the diagonal which means a lot of tile cutting. It worked great for me and is still in good shape. I don't think it would hold up for a professional tiler since the pivot points do not have bushings or bearings but there is no slop in them on mine yet. I also notice the price keeps coming down on them.
I liked the two sets of impact sockets and plier set.
The thumb ratchets were a waste of metal. The battery charger I bought 5 or so years ago didn't do very well either. The bench chainsaw sharpener/grinder is marginal. If they had spent another dollar or two on the clamping system to hold the chain in better it would have been great.
