Break apart to easily, do not last as long as others

I typically buy my cutoff discs from Harbor Freight. 10-packs can be purchased on sale for $7.99 or less. I decided to give they discs a try in spite of other users complaining about exploding discs. After a month of use, I can say that Ive not had any discs explode (care in not binding when using a cutoff wheel is important) but I quickly discovered that they dont last very long. I wasnt sure to what degree because I didnt have anything to compare to since all of my HF discs were used up. I recently picked up a 5-pack of HF discs for $3.99 and found that Im using roughly 2-3 of these discs for the same amount of cutting as one HF disc. With these discs pricing out at around $.43/disc, compared to HF at $.85/disc, the value just isnt there. Especially when you have to stop twice as much to change discs. Plus the edge starts to look really ragged once they get down to half size.

I disliked the fact that the wheels flexed when I used them
