I use this product on my auto windshields inside and out as well on my motorcycle windshield. It is good at dissolving bugs on exteriors and good at dissolving evaporated solids and oils that build up on the inside of the windshield. dissolving bugs without much rubbing is critical on plastic windshield materials and it does not tend to steak. It may take more than one application on auto interior windshields that get oily build up from interior materials.

I haven't seen much weight change, but it definitely does suppress your appetite. The caffeine works great to wake you up in the morning too. However, it has also caused slight insomnia and stomach pains/nausea if I eat too much. And after the initial wakeup jolt in the morning, I feel sluggish and grouchy. Personally, I think the cons outweigh the pros. I just feel like it's doing more harm than good to my body.

I bought the Studio 2015 Deluxe. Was excited to get it and upset that the disk would not load. The computer kept spitting it out, saying "load a disk." When I examined the disk, I saw that it was never burned! I was very disappointed in this Hallmark product.
