Pros

- Great for renters or temporary use
- Packs flat for travel
Cons
- Suction cups can loosen on textured or cold glass
- Less durable long-term
If you're renting somewhere you might move from soon, or you just need something up fast without leaving marks, this is the practical choice. It uses suction cups around a rigid frame edge and comes down in seconds. The trade-off is reliability — on very cold glass or textured windows, the suction can weaken over weeks, so you may need to re-press it occasionally. Also genuinely useful as a travel blackout blind for hotel rooms if you shift-work while travelling.
