I think Favi is Saaria as well.
These are extremely inexpensive bottom of the line products. But, for the money, you really do get your money's worth.
The biggest issue with this, as it is with all roll-up screens, is that if it is used, it may already have waves in the material. If it does not, then it will develop waves over the next year or so which will significantly diminish the quality of your viewing experience.
If 120" is the right size for your viewing, then I would consider the following:
1. Do you really need a roll up screen or can you go with a permanently fixed screen? For the $$$ permanently fixed screens are far superior.
2. Are you okay with the reality that waves WILL occur in your $250 screen in the next year or two (if they aren't already there)?
3. If you aren't okay with that, then are you prepared to dish out more moey for a tab-tensioned electric screen?
4. If not, then I would go with a far less expensive manual screen, which will still get waves in the material, but will do it for $100 instead of $250.
5. IME, a nice DIY fixed screen for around $100 can beat out a screen with waves in it for quality any day of the week.
