I bought these for a test project. Upon completion of the test of 5 of these I found:- Inflation: Very large (Not intentionally overinflated)- Strength test: Very difficult to pop under 150 lb weight, and will not pop on grass as easily as the standard balloon.- Outside friendly: Yes- Color: Red seems to have no transparency like one of the pictures; White is completely opaque; Blue is semi transparent, but not truly clear.- Best uses: While balloons can be used for a multitude of purposes, these are great for indoor and outdoor activities, and as long as they are not pushed too far beyond their listed ratings will in most cases be surprisingly durable and large.- Overall: 95/100- Quality: 10/10- Notes: One of the white ones had a small pinhole, but it's best not to judge it too harshly as the balloons hold up very well in general. If you will be storing these for long periods however, you should store them in a dry dark place as these are 100% biodegradable and the quality may deteriorate with time.Overall, the quality is one of the highest in terms of strength and durability.
