Unfortunately when I used it the middle size expander broke. Review: Poor material quality and questionable design - I was not expecting a professional level quality tool as the price point was so low but, as with many of the tools I've purchased from desertcart, they usually work fine in my garage. Not so with this one! It failed during the first use. I was simply trying to remove the pinch in a muffler left from the previous use with a u-clamp. It really hadn't made much of a change in the shape of the pipe when I noticed it was suddenly easy to tighten for about a turn and a half. I took it out to see if the pipe could slide in the muffler and realized that there was some binding when loosening, this was due to the fact that the taper closest to the hex had failed and mushroomed out. While looking at this design, there are really two problems: Poor material and the ramps of the tapers are entirely too steep. You can see the cracks in the part that were the failure but they were caused by a soft material that initially allowed the cooperative part to dig into the surface as opposed to sliding along it. The deep gouges are visible in the cracked part while they are not present in the opposite taper that should be doing the same work. All in all, even if the material quality was better, the design requires too much effort from the screw due to the steep ramp angles. Look for a different design as well as a different supplier for a hobbyist pipe expander. ## Features - 【FUNCTION】 The SCITOO 3-Pieces Pipe Expander Spreader Tool Set is designed to quickly and easily straighten clamp dents and clamp marks in mufflers and tail pipes, and stretch pipe openings or fix damaged pipe ends. Can be use with a hand ratchet or breaker bar and also a hand wrenches. - 【CORRECT USE TO AVOID DAMAGE】 Only work with all 1-1/8inch to 3-1/2inch ID thin-wall pipes. Please pay attention when using: (1) When expanding, the beveled steel cones of the expander must be fully inserted into the pipe, not half; (2) Try to use a manual ratchet or manual wrench to turn the pipe support tool to expand the pipe, rather than electric Ratchet; (3) Avoid twisting the expander with excessive force. - 【FEATURES】 This Tail Pipe Expander set includes three different expander sizes, can work to all 1-1/8inch to 3-1/2inch ID thin-wall pipes.
