One of the best qualities of Korky is its affordability while assuring users of its durability. Korky products are priced much lower than their counterparts and are all made in the USA.

Buying a complete set can be more cost-effective because of Korky's affordable pricing if you need just one part for your toilet. Simply keep the other parts for future use.

Korky is known for creating products that have a universal fit and can be used on nearly 90% of toilet brands.

Even older toilet models can benefit from a Korky repair kit, so you don't have to replace the bowls and tanks because you can't find valves and other necessary parts.

3. Easy Installation

Most customers praise Korky for its easy-to-follow installation guide. This is perfect for those who don't have experience in DIY projects like fixing leaky toilet valves.

1. Loud Valves

A common complaint from most Korky users is the loud float valves.

While it generally does not affect the product's capability in flushing the toilet, the noisiness of the float valve tends to annoy users, which is why they would choose the competitor.

2. Leaking

Some Korky users have complained about leaking issues from the product, which has caused their water bills to skyrocket.

While this issue can be fixed with Korky's warranty, it should be an issue that the brand has addressed early on due to multiple complaints.

3. Product Failure

While this is rare, some users have complained of the product completely failing only after weeks of use.

Some users point out that the materials of the Korky products are made of poor materials, which is why the product has trouble functioning properly.

1. Not A Univeral Fit

One of the issues some customers complain about with Fluidmaster is that the products are not universally compatible. Some brands like Gerber and Kohler are not compatible with the Fluidmaster parts.

It can also be a little challenging to fit Fluidmaster toilet parts on older toilets because they have parts that are a little bigger than their competitors.

2. May Require Extra Pieces

Some users complain that the Fluidmaster kits have only the exact pieces you'll need for installation.

Unfortunately, there are times when you're bound to lose one bolt, or the toilet that you have will require more than the pieces they have. Because of this, some users had to buy extra parts to complete the installation.

3. Imported Parts

Unlike their competitor, Fluidmaster parts are not made in the USA. Most parts are imported from Mexico and China, which some consumers do not favor.

However, despite their parts being imported, Fluidmaster still holds high standards in their production facilities in creating their toilet replacement parts.
