We're new at the Arduino stuff, and these little doodads looked like fun. We want to build some sort of robot so we've ordered a ton of different pieces and are working on it. The soldering is solid and everything appears to be in ship shape.

This set of five ultrasonic distance sensors is exactly what I needed to add to my growing collection of components for my students' Arduino projects! I have purchased several starter kits, but there are several students who have begun projects which require distance sensors, and this was the best way to go! As imagined, buying in bulk is cheaper than buying singletons. Even if buying in &quot;bulk&quot; means five.

I have been so very satisfied with the quality of the product coming from this company. We have not had a high fail rate of components, and service has been extremely quick. Everything arrives in protective packaging, and in great condition.

I don't have a lot more to say about these distance sensors - they do what they are supposed to do. I do want to emphasize how great these products are, how much students learn from participating in electronics programs and using the Arduino products.

I received this product at a reduced cost in exchange for my review, and I am giving you my honest review. I have purchased so much from this company for my students, and they have put the products to the test! Excellent products, excellent service, excellent learning!
