  • Excellent!
Good product.

  • It performed well while doing my plumbing line. Nice addition to my tools. 👍😊
The 42mm wide-opening plier offers an easy adjustment feature, which, in comparison to my existing tools, appears to have average build quality. It exhibits a slight degree of play; however, it effectively serves its intended purpose. Recently, I utilized this tool while working on a plumbing line for an embedded auto sprinkler system designed for my garden, to distribute a fine mist within the planted area. Given my use of a smaller diameter pipeline, the tool's easy adjustment mechanism, coupled with the rubberized protection on its handle, provides a secure grip alongside my other tools. The plier's effectiveness is commendable, and its construction from chrome vanadium steel—known for its high tensile strength—suggests it may have a long service life. Nevertheless, I remain uncertain about the material used at the adjustment connection point, where the tool facilitates adjustments. I hope that this component is also rustproof and sufficiently robust, as it is critical to the integrity of the grip's force. At this time, I am satisfied with the performance of this wide-opening pair of pliers. ... show more

  • Lightweight Pliers
These 7 inch locking pliers arrived securely packaged in a bubble padded envelope. They feel lightweight and balanced in the hand, making them suitable for both right - and left-handed users. The build quality is decent overall, but there are a few design concerns worth noting.The rubber grip extends only about 4.5 inches up the handle, which feels too short for comfortable use. My hand naturally rests at the seam where the metal meets the rubber, and that edge can be uncomfortable during extended tasks. The grip also appears to be loosely fitted, with no visible reinforcement. This raises concerns about durability and potential slippage over time. Functionality is solid in terms of locking performance. The pliers clamp securely and hold their position well. However, the locking mechanism relies on a small metal piece at the pivot point, which may wear down with repeated use. It’s functional now, but long-term reliability is uncertain. Size wise, they’re compact and easy to store, ideal for light duty tasks around the house or in a toolbox. Cleaning and maintenance are simple. Just wipe them down after use to keep them in good shape. Versatility is limited by the grip comfort and potential wear on the locking mechanism. For occasional use, they’ll get the job done, but they may not hold up under frequent or heavy duty applications. At $20, these pliers feel overpriced given the design limitations. ... show more

  • Start the Countdown to Obselescence
Arrived pre-rusted. Not a great start for rust-resistant pliers. The surface is quite a bit more rough than the images imply. The metal texture tells me they're only going to rust worse as time goes on. The clip mechanism is usable but the build looks like they just saw how a nice set of pliers worked and used a first year engineer to rebuild it in his back yard. It's a semi-open spring clip applied to the release bolt that hangs out. Definitely purchase at your own risk. I can say they're pliers. At 9.99 I'm too lazy to return them but I wish I'd read the reviews better before buying. ... show more

  • Very Nice!
Bought these 7" groove-joint pliers for occasional shop and car maintenance use; grip is excellent and build quality presents well. V-jaw bites cleanly on pipe and hex without slipping; jaw faces align true with minimal play. Multi-position adjustment gives plenty of range, and the 42 mm max opening is generous for the size. Chrome-vanadium steel with TPR grips feels durable in hand. In my review photos, I took photos of these pliers next to my premium German pliers; they are surprisingly comparable in bite and finish for a fraction of the cost. Fully functional, no wobble, and the pivot tracks smoothly. ... show more

  • Awesome little channel lock pliers so far.
I own various channel lock pliers but nothing in this smaller size, and nothing with a locking quick adjustment for the jaw. I really like the adjustment mechanism on these, it's quick and secure and easy to do even in rather tight spaces. The finish is a little rough, but this also isn't a very expensive tool so I mostly give that a pass. The action on mine feels smooth and the pliers appear to be straight and true when clamping down. The biggest concerns are will these hold up, I think for most people around the house these will be fine. If you're a professional and work your tools hard, you may want to consider alternative options. I still have other channel locks I'll use for more intensive tasks, but the size and convenience here will ensure these channel locks stay in my rotation. ... show more

  • Handy to have for a good price
I'm so glad I got these pliers for my latest bathroom project. I was installing a bidet, and the plumbing connections can be a real pain to get to. The description mentioned an "Extra-Wide 42mm Opening" and a "V-Jaw Grip Technology," which sounded perfect for the job. They made it incredibly easy to get a secure grip on the nuts and bolts in a tight space. I also really liked the "One-Handed Quick Adjustment" feature, which saved me a lot of time and frustration. The entire installation was a breeze, and I'll definitely be reaching for these for future plumbing tasks around the house. They are pretty durable and function as they should. ... show more
