About Master Wrench

Master Wrench claims to be a tough, contractor-grade tool that uses spring-loaded jaws and a “pit bull-like grip” to remove any nut or bolt in seconds without damage, and with just one tool. Because of this, Master Wrench is claimed to be perfect for stripped nuts and bolts, pipe fittings, rusted old bolts, and more.

In addition, because the Master Wrench is claimed to do the job of 50 other tools, it can help save you time, hassle, and money.

If you have even the most basic toolkit, you know that it can quickly become cluttered and disorganized, leaving you constantly searching for the right tool. But is Master Wrench worth your money, and can its 50-in-1 design really save you time and hassle? Consider the following:

How Does Master Wrench Work?

Based on the product’s commercial, each end of the Master Wrench is shaped like a crescent, which is spring loaded so that the opening becomes bigger or smaller depending on the size of the nut or bolt you’re working with. In addition, each crescent contains serrated teeth that grip the object you’re attaching it to.

Then, as you apply force to the Master Wrench, these teeth clamp down on the nut or bolt and keep it in place as you turn.

Does Master Wrench Work on All Sizes of Nuts & Bolts?

According to the Master Wrench website, the product works on all nut, bolt, and pipe fitting sizes from 9mm to 36mm (about 0.3 to 1.4 inches). In most instances, these sizes should take care of most of your needs, although if you commonly work on automobiles, you’ll certainly encounter some nut and bolt sizes that the Master Wrench won’t be able to accommodate.

The Master Wrench-Nebo Grip All Connection

When searching online for “multi wrench,” we came across a product named the Nebo Grip All that appears to be essentially identical to the Master Wrench (we’ll talk more about this in a moment).

While we can’t confirm if these two products are manufactured by the same company, or if the Master Wrench is a rebranded “As Seen on TV” version of the Nebo Grip, the similarity between the two is uncanny.

Other All-In-One Tool Options

Finally, keep in mind that there are a wide variety of all-in-one tools and hardware that you can choose from, including the Skil Secure Grip and Skil Ratch-N-Lock. On top of this, many of these types of tools will be available through local hardware and home improvement stores, which could save you a good chunk of change on return S&H charges (more about this next), not to mention the hassle of shipping it back to the manufacturer.

Are Customers Happy with Master Wrench’s Performance?

Master Wrench appears to be a very new product (URL registered March 2015), so there weren’t any online customer reviews available at the time of our research.

However, as we mentioned above, Master Wrench and Nebo Grip All appear to be essentially identical products. As such, the Nebo had 5 Amazon customer reviews, with an average rating of 3.2 stars. While some customers appeared to be happy with its performance, others complained that its size makes it somewhat cumbersome, that the crescent’s teeth can easily become worn, and that it may damage a nut or bolt if you’re not careful.

Master Wrench Pricing & Refund Policy

Master Wrench is priced at $29.99 plus $7.95 S&H, and comes with a lifetime warranty.

In addition, Master Wrench comes with a 30-day return policy, less S&H charges. While there’s no indication on the product’s website how much the Master Wrench weighs, it’s likely going to be relatively expensive to ship it back to the manufacturer in the event you’re dissatisfied, which could really cut into how much you ultimately receive as a refund.

With this said, in order to request a refund for your Master Wrench, you’ll need to contact customer service at 844-281-1536 for an RMA number.

Can Master Wrench Replace 50 of Your Tools?

While the Master Wrench certainly has a unique design compared to the competition, there aren’t enough online customer reviews available to gauge overall satisfaction levels or to discern what you can reasonably expect from using the tool.

Based on existing reviews for the Nebo Grip All though (an all-but-identical product), it seems that you’ll have about a 50/50 chance of being satisfied with your purchase. Because of this, we might recommend exploring local options before placing your order for Master Wrench.
