Real Reviews from Tiger owners:

Since we’ve covered the features and the Pros and Cons for the Tiger PDU-A40U-K earlier, now it’s time to know what the general masses have a say regarding this water boiler:

“It is the ideal kettle for me. To put in detail, the 3.0-liter is my preferred variant since I have a large family and we’d certainly want to have enough hot water for the whole day. We’d use it for soups, instant noodles, coffee, tea, and the like. It’s easy to use and it’s easy to monitor the warmer’s current temperature due to the LED gauge. It’s easy to maintain too due to it being easy to clean and its dechlorinate feature.” — Lissa Johns


“Almost a perfect water boiler for me. I love its temperature settings; I love its consistency in being able to dispense hot water or boiling water whenever I want it. I can keep track of the water levels of the kettle due to that water level gauge window but I have a suggestion or two or more to further improve this kettle. My first suggestion is that it must have an “on” switch. Admittedly, turning it on is easy through the magnetic cord but I’d prefer a switch so that I won’t have to plug and unplug it repeatedly when in use or not.” — Katherine


“Amazing product in my opinion. Sure, I may end up plugging it repeatedly whenever I want to use it or not but in the end, it is still a very convenient water boiler. My family loves this water boiler so much – my husband loves to take some of the hot water for his morning coffee, I make oatmeal or hot milk chocolate drinks for the kids for breakfast and I spare some water for myself whenever I want a piping hot cup of tea.” — Maria Cortez


“Been using this wonder of a water boiler for quite a while and I’ve been very pleased with the hot water it gives to me on a regular basis. Quite surprised that it is cheap too, worth the purchase!” — Kevin


Overall, the Tiger PDU-A40U-K offers excellent performance all-around when it comes to boiling water. It is easy to maintain and to use. Many users have praised it for those reasons.

The only caveat is the fact that the PDU-A40U-K lacks a timer and has no café drip. This means that it needs a bit of babysitting and cannot dispense precise volumes of water. With a smaller water level gauge window, it gives some degree of visibility however, It can be a little trickier to estimate how much water is left inside the container.

The PDU-A40U-K doesn’t have an on or off switch button and relies merely on the magnetic cord to be powered up and lastly, it doesn’t have energy-saving mode support which could make it even better. Despite the few flaws it has, the Tiger PDU-A40U-K still has a following because it has a cheaper price tag and could be an attractive choice for those who are trying out a water boiler for the first time.
