No need to be ashamed, if it works it works. Whetstones look cooler but they do the same job. I actually bought the same device at a local knife store for my parents and the clerk said it was perfect if you just want to get sharp knives and be done with it. Whetstones or professional sharpening is more useful for pros or knife hobbyists/enthusiasts.
In the comments it reveals this guy is using the sharpener wrong by doing way too many pulls with too much pressure.
The cheap ikea one is fine, it will not wear out your blade. 2-3 pulls at very light pressure, no need to learn how to use a whetstone properly, perfect UX for those who don’t typically sharpen knives.
I am ashamed to admit it, but I have been happily using this 5,99 EUR IKEA knife sharpener for nearly 10 years know:
