## Verdict

An aging lamp-based 1080p unit coasting on reputation. Its light source degrades on a schedule modern lasers made obsolete.

## For

- Well-liked 1080p short-throw design
- Longstanding reputation on gaming-projector lists

## Against

- Lamp degrades quickly and noticeably compared with laser
- Ongoing replacement lamp costs
- 1080p resolution is dated
- Poor 2026 buy at its street price; current lasers outlive and outclass it

## Flagged as one to avoid

This product entered 3 of 7 runs as one buyers cross-shop but should not buy, rather than as a pick. It is published here rather than dropped.

## What this tier means

- F: Avoid. The evidence points you elsewhere.

## How to read this

- Each category is researched in four independent runs, one per lens (expert consensus, value, reliability, community pulse). Every run ranks a board of candidates that deliberately includes products buyers cross-shop but should avoid. Placements score on a ranked ladder (LP), and tiers are derived from LP, so no tier is ever assigned by hand.
- LP is this product's points on its own category ladder. It is comparable within a category and not across categories.
- Link status reports what our pre-publication link check found when it fetched the cited URL. It says nothing about the quality of the review.
- A citation with no usable link is listed rather than dropped, and is excluded from the counted total above.
