Waste my money
Got the gauge set today and tried the temperature clamps. I put both into ice water. One reads at 36F and the other one read at 37F. When I put them into boiling water, one reads at 206F and the other one reads at 207F. When temperature is low, it has high positive offset. When temperature is high, it has high negative offset. No way to calibrate it. Garbage set and waste my money.

Works great!
Temp clamp broke after second use. Looking to see if they sell replacements. Otherwise this thing is great. It does all the calculations for you. No more converting psi to temp and subtracting temp etc. love this thing.

Hoses are junk! Manifold gauge is fine...
Odd they rate these hoses at 3000PSI (Ha!) yet at 78 PSI they leak at the crimp. The hose itself MAY take that pressure but no point in all that if the crimp joint is garbage! Sent it back and bought same type of unit from another seller and bought a Yellow Jacket hose set! Sadly the yellow Jacket hoses cost more than this manifold set!
