Very good product. VFM. Strong light and durability. The glue is not very strong but it doesn't bother me as it can be easily fixed since it works well for what it is intended for, which is the light.

Very good tape with very strong light. Be careful, the bottom side is metallic so it is not very flexible. However, it can be cut comfortably every 5 cm.

Just fine for a simple and cheap vacuum. I've had it for 2 years for changing water without the funnel in front because it's for a small aquarium.

For a quick and multiple test, it's just fine. However, it's not as reliable as the individual and specialized ones. It's also difficult to separate the results.

VFM. They are perfect. It has everything for amateur use and for adults and children. I use it all the time.
