Good impregnation spray, but if it is better by Nano?

Since I also own such products like trying out and it is important especially in such products on the advice, I will write about this product a.
I use this spray to impregnate high quality leather handbags and suede boots (eg Uggs).
What stands out in comparison to other sprays and very pleasant as is the pretty thrifty and accurately metered nozzle. Compared with these I could impregnate Dose 3 pair of boots and a handbag, whereas I've done with other sprays only two. In addition, the nozzle does not cause soaking / drowning of the leather.

The spray is definitely good and does what it promises. Especially with beigfarbene boots it not only keeps the moisture but also the dirt very well away. A regular repetition of all 1-2 months, however, is unavoidable even with this spray.

3 Points are awarded from me, since I compared to other sprays Collonil (all of which are very good) can not detect a really noticeable difference. I've done with some of nanoproducts (Sonax glass cleaner) good experiences. These but it seems to me likely to be marketing.

Therefore, very good product, but recommended for other Collonil products.
