Conclusion​

Product	PROS AND CONS​
ViewSonic PS502W​	Pros: • Good picture quality and clear focus • Bright enough for rooms with some lighting • Compact and lightweight design, making it portable • Variety of inputs for different video sources • Effective for basic projection in controlled environments Cons: • Menu navigation is difficult and not user-friendly • Noisy fan can be distracting during use • Best performance requires precise positioning relative to the screen • Not ideal for rear projection due to bright spots on the screen • Issues with reliability, such as lamp failures and image quality deterioration Overall Impression: The projector offers good value for the money, especially for basic projection needs in a controlled environment like meetings or lectures.

Optoma ML1080ST​	Pros: • Easy to set up • Brighter than most portables; good even in dim light • Small, light, and efficient; fans operate quietly Cons: • Requires constant focus adjustments • Large cord Overall Impression: This portable projector offers excellent value for its price, especially for gaming and movie-watching.
