Product review (1 stars): Different than picture
The clamp shown in the picture has a solid strap on the inside (the area with no perforations) that appears to wrap around nearly 40-50% of the diameter. This is done to ensure that the clamp compresses the tube, rather than gauging in on one spot - it also helps ensure the perforations don't cut into the tube.

The clamps that I received have a solid strap on the inside that is only about 5% of the diameter. This is no different than the $0.50 clamps that are sold at big box stores, but I paid almost $7.00 each for these!

I am not impressed.

The writing indicates this is a "POWER SEAL" made by "BREEZE" in the "USA".
