The quality is very good. It rusts nothing and scissors and forceps go easily.
Spatula I use to straighten out again to the gravel, but I need hardly ever. Not so with scissors and forceps. With scissors I naturally stop short aquatic plants or cut them out. With the tweezers I use plants, reading worm or plant debris from the water.
Even though I'm really happy with this set, I would have still 2 proposals. First, the tools could be a little longer. Not that I do not want to make your hands wet to me, but with a correspondingly large aquarium you yourself with this tool even more so his trouble.
In addition, the scissors might have a slightly larger sectional area. These could be slightly curved. This would not facilitate the cultivation of aquatic plants considerably.
Conclusion: Good helpers in the aquarium care. I would be, even at this price, choose again and again for a purchase.
