Surprisingly well made.Zero issues crimping or cutting. The square "flip chip" for switching from cut to crimp is very tight in the bore, so it takes some effort or a pair of pliers to turn. The handles are definitely too wide for one handed crimping, so be prepared to have both hands free for use with the tool. The provided clamps were adequate.The crimp area is not perfectly squared or recessed like an Oetiker or Shark Bite clamps are, so you have to somewhat push forward when beginning your crimp to keep the crimpers from sliding off the clamp until they have some bite.They're sturdy and grip just fine once they've been crimped, though, and have the appropriate ASTM markings on them. The provided cutters worked great - cut square through some stiff PEX tubing like butter.
