Good value for money
Works well for obstacle avoidance. The detection range is accurate within the specified limits. One sensor was slightly loose in the header.

Excellent for Arduino Projects
These sensors are very responsive and easy to calibrate using the onboard potentiometer. Perfect for my line follower bot.

I bought five of these for a robotics kit. All of them functioned correctly out of the box. Highly recommended for hobbyists.
