The product is well known, so no surprise here. WaecoAdler Barber etc all sell the same thing, just a different badge name, made in China by a contract manufacturing firm. If they really wanted to improve the quality of the product they would make the entire tune length from the evaporator to the compressor out of copper. The thin tube walls on the alloy tubes are very brittle and suscetible to corrosion, chafe and wear. Not really yacht quality. The mfgs. should spend a dollar more and make these tubes higher quality out of copper. This will be the last time I replace this product.
