Flex Tools may not be one of the biggest names in the marketplace, but this German manufacturer has been making high-quality equipment since 1954. They feature alongside top names like DeWalt and Milwaukee among the best power tool brands ranked and have a reputation among industry experts for producing pro-grade gear.

The Flex Stack Pack system is another entry into the extremely competitive market for rolling modular toolbox systems. The Flex version offers around 40 different interlocking units to organize and transport tools, accessories, fasteners, and other consumables. Comparisons are bound to be drawn with Milwaukee's Packout and DeWalt's ToughSystem, and Flex pricing suggests that's the market they are aiming at rather than competing with well-known DIY brands like Craftsman, Ryobi, or Stanley Black+Decker.

Taking on those two leading brands is quite a challenge, so the big question has to be, are the Flex Stack Pack Toolboxes worth buying? For comprehensive answers, we looked at specifications and checked out both independent reviews and feedback from customers at several major retailers. Here's what they had to say.

The main Flex Stack Pack units are made from impact-resistant polypropylene with aluminum-reinforced corners for jobsite toughness. They offer weather protection to the international IP65 standard. There are nice touches like sprung catches that automatically lock the units together when you place one on top of the other and gas struts for the lids. The telescopic handle is removable, so the system can be disassembled and carried on a covered truck bed.

One independent reviewer concluded that "I think that Flex Stack Pack is going to make some competing brands sweat a little. The new system offers a lot, and with no compromises I could find yet." Another, when comparing them with Milwaukee and DeWalt, said, "After looking at what the Flex Stack Pack has to offer, you might just change your mind."

The vast majority of customers are equally positive. At Lowe's, it gets an average of 4.7 stars and is "praised for its durability, functionality, and customizability". One buyer summed up the thoughts of many when they said, "Durability, balance, flexibility, storage options, [and] product quality are all superb." It's a similar story at Amazon: "Great storage, great quality, and looks and functions better than the big-name tool brand options. Love it!" Similar thoughts are echoed at Acme Tools, where it also gets 4.7 stars. Wherever you look, most reviews are happy to recommend the Flex Stack Pack toolboxes.

With so many interchangeable units, it's difficult to make direct comparisons, but most brands offer a 3-box general-purpose set. If you buy the Flex version, this will cost you just shy of $330. The equivalent Milwaukee Packout is more or less the same price, and the DeWalt ToughSystem is around $40 less. If you're a contractor or other professional, making your choice is going to be a question of looking at the specifications in detail to find which suits you best. It's also worth checking the rest of the range if you imagine expanding the system over time.

For DIY enthusiasts, that's not really the issue. If that's you, then the big question is whether you really need portable toolboxes of this quality or if something less expensive would be okay. You could, for example, keep your tools organized with a Ryobi storage solution. A 3-box set from this popular brand can be yours for $179. For an even more budget-friendly stacking system, check out the other rolling toolboxes at Amazon worth buying. There's one from Stanley that's just $112. If you're a pro, the Flex Stack Pack toolboxes make an attractive alternative to more established brands. If you're only going from the garage to the yard or occasionally popping round to a buddy's place to help out, there are other systems that can do pretty much the same job for an awful lot less.
