Well built, sturdy enclosure.

This enclosure is everything promised in the product description and more. I purchased it for my M.2 512 GB drive after an upgrade to a 1TB drive in my laptop. This enclosure supports trim which is a must for SSD's. Trim was my number 1 requirement. Startech support and delivery was great!
