I bought mine from daraz.pk about a year ago and have used it a lot. Never had any issues with it and it's good for novices. I don't exactly remember what I paid for it, but it was somewhere between 15-16k I think.
Mine didn't come with a foam lance, so I bought that separately for about 3.5k I think. You will need to figure out a way to attach it to your normal tap since the pipe on mine kept coming off. I used normal screw clamps (about 20rs each).
The filter where the inlet pipe attaches will get dirty, so use a pair of needle nose pliers to remove and clean it.
Don't expect to see too much foam action since it is only a 110 bar machine. If you use about 100ml of shampoo with 900ml of water, you'll get good results. Using a concentrated shampoo-water solution will get you more suds.
Mine is the K2 compact, so the underside does get scuffs because I do drag it when I'm using it. I'd recommend attaching a piece of foam/cardboard underneath if you're too picky about getting it scratched. I've kept mine as is though. Always remove all the water from the machine by running it for about 30s after removing the water supply pipe. If you don't do so, there's a slight chance water will seep into the motor and cause it to short circuit. Turn the machine on before you turn on the water supply to avoid any air bubbles from forming.
