- Material and build quality — Look for durable materials that hold up over time, not just look good in photos.
- Reviews and ratings — Stick to products with 4.5+ stars and a solid number of verified reviews.
- Price vs. value — The cheapest option rarely wins long-term. Our top picks balance both.
- Return policy — Amazon's return policy makes it easy to try risk-free if you're unsure.
