I have read some have seen the plastic slides were cracked new out of box. Several years ago i noticed mine were cracked, i was able to shut mine and I haven't opened it since. I also have read that some have taken it to a glass shop to have the seal replaced on the glass. I have been researching this for many years, the price doesn't justify the option repair. I thought about taking the slides out and cast them in aluminum or would a CNC work. Basically, its just a bad design.
