Purchased this for my husband for Christmas. It's what he asked for. Already use this product, and used it well. We removed leftover linoleum glue from a wood floor and were truly amazed at how well it worked. This could come in handy for helping remove stubborn wallpaper and any globs of caulk or silicone you may have gotten sloppy with. Well constructed and I can see various uses for this product. I guess I'll let him use them first.
We added this to our current Fein accessory box and it works great. Depending on materials (scraping old roof sealant for skylights or vents, etc), this will wear down of course and as a professional outfit, we need to keep a few on hand.
