Well, it does the job, but I got almost the exact same thing from a well-known Chinese shopping site for 2 euros. Believe me, they have various options. So, while it is decently priced, it is not worth it beyond a certain point. So, is it worth buying? Not even close for this amount of money.

Positive:
1) Quality and durable construction.
2) Does a good job with dirt.
3) It has a convenient handle in the center for easy removal from the bucket.

Negative:
1) For washing with 2 buckets, it would be good to have a version with a smaller diameter that fits in a smaller bucket.

Overall satisfied.
I would recommend it as this solution is almost a one-way street.

I give it 3 stars because the price is really high. I searched a lot to find similar ones from other brands but I couldn't find any. Everything plays a role and you have to choose carefully to fit in the bucket. These grids fit in buckets with a wide bottom. Special buckets like these are expensive. The grids don't fit in most of the sponges we use. Meguiar's company currently has their bucket for 12 euros! It's a great opportunity since a while ago they were selling for 15-16 euros and they were even out of stock. Even 12 euros is an expensive price, but you won't find anything cheaper! The thing is, you buy these once and you're done! For someone who already has a worn-out car and doesn't care about doing the perfect wash, all of this is a waste of money. But for those who have a brand new car, flawless, it's worth buying the right materials and washing equipment if they want to wash their car themselves.
To get back to the point, I give it 3 stars solely for the use of the plastic grid! It really holds a large amount of dirt at the bottom of the bucket, and it helps when you dip the microfiber sponge in the bucket to rub it on the grid and clean it from some dirt that doesn't easily come off under other conditions from the sponge.
Overall, it's quite expensive. I bought 2 grids and 2 buckets, and I spent a total of 70 euros!!! They are of good quality, hard plastic, they don't break easily and they are durable.
Because I enjoy washing my car by myself as a hobby, I think that even though it's an expensive purchase, it's worth it because with the 2-bucket process, you prevent the color of the car from fading and the creation of spiderweb marks. Of course, it also depends on the fact that I have a new car. I recommend to those who wash their cars themselves to buy high-quality cleaning products. It's a shame to think that you have spent 12-15-20 thousand euros, a lot of money, and then get stuck on the money that a good quality product costs just to save 30 euros.
