In my own experience, the value of tab tensioning is to stop the edge curl that happens even with very good non-tensioned screens. I have used Stewart, Da-Lite, Draper, Screenline and others in various configurations.
Tab tensioning doesn't sort out issues where the screen surface as a whole shows ripples. That could be down to poor quality materials, or sloppy construction, or improper installation: Getting the screen case level makes life so much easier, but you'd be surprised how many DIYers and even some pro-installers are slap-dash when it comes to this.
There's a marked step up in price between the standard and tab-tensioned electric screens on the Platinum site. I wonder if the surface for the tabbed screens is a better quality compared to the ordinary electrics? Just a thicker, heavier, vinyl surface would be enough to help keep surface ripples under control. That, and a decent diameter roller plus a counterweight bar that's straight.
Cheap electrics are definitely bad VFM IMO. Optoma's bundled screens were a case in point: Cheap, but worthless come resale time because of the screen ripples.
The Platinum tabbed screens look okay from the limited pictures above. I'd give one a cautious recommendation for someone on a tight budget. I doubt that the tab tensioning would be completely effective, but a thicker screen surface and better construction could well offset many of the problems of cheap £100-£200 standard electrics.
)... and the only screws i can see anywhere that remotely look like they could be them are the ones in the pic... can anyone help please - are they them?????
