Frequently Asked Questions

Which lens cover is better for the HY300Pro: Yaregelun or Trevandoria?

I’d give the edge to the Trevandoria cover overall. The key difference is material — the Yaregelun uses rigid ABS plastic while the Trevandoria is made from soft, flexible TPU. That TPU flexes during installation so it won’t scratch your lens, and it grips the projector body with a slight interference fit that keeps it secure during transport. The Yaregelun is fine for basic dust protection on a stationary projector, but the Trevandoria is the better all-around choice.

Is the Trevandoria cover worth paying more than the Yaregelun?

For most people, yes. The Trevandoria uses thermoplastic polyurethane which stays soft and pliable, meaning it absorbs impact if bumped and won’t scratch the lens when you put it on. The Yaregelun is a simple ABS cap that’s cheaper, but that rigid plastic can actually scratch your lens if you’re not careful during installation. If you ever move your projector around, the Trevandoria’s secure hold alone makes it worth the jump.

Will the Trevandoria cover fit the HY300Pro or only the HYPRO300+?

The Trevandoria is specifically listed as compatible with the HYPRO300+ Smart Projector, not the older HY300Pro. The Yaregelun is explicitly made for the HY300Pro. If you have the HY300Pro, the Yaregelun is the safer fit — though the Trevandoria’s slip-on design might still work since the lens housings on these models are often very similar. I’d check your projector model carefully before buying either one.

Which cover is better for traveling with my projector?

The Trevandoria by a long shot. It has a slim-profile design that adds minimal bulk to your bag, and the TPU material’s interference fit keeps it locked onto the projector during transport. The Yaregelun weighs only 0.688 ounces and is compact, but its rigid ABS cap can pop off easily if something bumps it inside a backpack. For travel, you want that secure grip the Trevandoria provides.

Can either cover protect against scratches and dust?

Both covers will block dust and prevent scratches, but they go about it differently. The Yaregelun is a hard cap that shields the lens from dust when the projector isn’t in use — just snap it on. The Trevandoria does the same but also protects against fingerprints, pet hair, and accidental bumps thanks to its soft TPU construction that absorbs impact. For scratch prevention, the Trevandoria is actually safer to install since the flexible material won’t scrape the lens.

Which cover has better build quality?

The Trevandoria feels more premium in hand. It’s made from durable thermoplastic polyurethane that remains soft and pliable, while the Yaregelun is molded from basic ABS plastic. The Yaregelun also has a 1.0 out of 5 stars customer rating from a single review, which raises some red flags about quality control. The Trevandoria’s construction is simply more thoughtful — it’s designed to match exact contours without blocking sensors or ventilation.
