Crush Research delivered a smooth overall experience. Shipping was fast, and the order arrived without issues. Their customer service stood out—responses were quick, clear, and helpful whenever I had questions.
I tried their RETA, and the quality seemed solid based on my experience. The COA was also trackable, which adds a layer of transparency that’s important when choosing a vendor.
One thing to note is that their inventory moves quickly, so popular items may sell out fast. Overall, a reliable option with strong communication, fast fulfillment, and good transparency.
