Customer Reviews on Keystone KSTAD50B

I have read reviews for the Keystone KSTAD79B from customers and summarised them below.

The Pros

One positive feedback raised is its price; customers have mentioned that the KSTAD50B is a good and affordable 50-pint dehumidifier. Another good point mentioned is its nice, compact design that includes the filter that is located conveniently on the top without any removal of fasteners or covers to get access.

The ease of programming a dehumidifying schedule via the software interface is also an  advantage.

Effectiveness in removing moisture; result from a test carried out by a customer show that the KSTAD50B can remove about 48 pints of water in 24 hours. This result is very close to the stipulated specifications. Another customer mentioned the KSTAD50B was able to reduce the humidity in a room from 84% to 67% overnight on high speed. Minimal operational noise generated by the Keystone KSTAD50B is also commonly mentioned.

Additional functions like the auto-shut (full tank capacity), in-built clean filter alert and auto-restart option were mentioned by customers to be desirable aspects that they look for in a dehumidifier.

The Cons

Design and material of the bucket is a mentioned con; emptying out a full bucket is mentioned to be a difficult process due to the sides that flare out. This will make spillage of water a likely affair. However, in a related comment, a customer has mentioned that this can be prevented by following the steps in the instruction manual. 

Unclear illustrations in the user manual, especially for the installation of the hose for the continuous draining option, is also mentioned. Wrong sizing of the provided continuous hose adaptor is not suitable to fit a standard garden house. It is mentioned to be smaller though a suitable hose can be purchased readily from a hardware shop.
