Raindrop gutter guards consist of several long thin rods of plastic that run parallel the gutter, on top of which sit numerous short rods that run perpendicular to the gutter. This creates hundreds of small slots in the guard that will admit water but keep out larger debris. This system is less expensive than micro mesh guard systems, but will likely still require the gutters to be cleaned out often if you live around trees that shed needles and small seeds. The company acknowledges that "whirly-bird" seed pods and pine needles can still make their way into the gutters, but maintains that these will be flushed out by the water running though the gutters. The guards can either be laid on top of the gutters or attached by slipping the back edge just under the shingle line. Raindrop also claims that this installation procedure will not void a roof warranty.

Rainbow gutter guards can be easily installed by the customer or done professionally. The company offers several videos on its website explaining the process. Rainbow also offers miter guards, rain barrels, electric gutter heaters, endcaps, and wide-mouth downspout outlets.

Rainbow does not publish its prices on its website. Its products are sold to DIYers through dealers in the Great Lakes, Mid-Atlantic, and Northeastern states as well as in the Pacific northwest. The company's transferrable 20-year warranty is not as long as those of its competitors, but customers must bear in mind that the installation is DIY, which increases the chance of mistakes.

Raindrop is a BBB-accredited business and has an A+ rating from that organization and zero complaints, but no presence on TrustPilot. The company has been in business since 2000. Despite the lack of consumer reviews, the company does have a considerable presence online, which leads us to trust their legitimacy and reputation.
