I think it's fine so long as you can determine the macros you want to eat, change them week to week (or at certain times), they're sanitary, and they're accurate.
Couple of similar services exist here in the states too. Some of the stuff ends up tasting like crap at the end of a week but this would likely eliminate any compliance issues stemming from food prep. On the other hand, it might prevent you from actually doing the food prep/measuring/etc. you need to learn to do to meet your goals. Overall, I think it's fine though.
