I bought the meat skewers to use on my Weber barbecue. They fit on the top perfectly. It is easy to load the kebab mixture (especially if you wet your hands). You can turn them over without the mixture spinning as it does on round skewers.
The only improvement I would make is to sell slip-on silicone handles as they can get really hot which I discovered when I went to pick them up without my BBQ gloves on!! My bad.
