We have the T-Fal one and have for several years. We don't use it overly often but when we do it works well. The basket is not the largest, so you're not making enough wings, fries, etc for a family of 4 or more. It can probably hold about 12 - 16 wings but I wouldn't push it beyond that.
The oil does cool down as you add items to the oil, so you would want it to be hotter to start with if you do a full basket of wings so that it doesn't cool down too much.
The unit cleans up fairly well. Once cooled, you flip the switch and it drains into the plastic tub on the bottom. it filters out all the chunks so the oil is fairly clean. We purchased a second bottom tub so we could have one for savory and one for sweet. Drain time takes about 10ish minutes. We take the tub and put it in the fridge for the next use. Once the oil is out, we wipe it down with paper towels then wash. Most parts are dishwasher safe, but we haven't done that.
Now that we live in the county and have access to a fire pit, we've done all our deep frying in a large cast iron pot. During the winter would be the best time to use it, but it still sits on the shelf and may has been used 2 times in the last 4 years.
