Good brush but not essential

With only hard floors in my house, I invested in this brush along our Dyson (dc33c), and I must admit that despite having attractive benefits, it is not indispensable.
This brush is light and very simple in its presentation: not available setting, it is the same width as the standard brush but is extremely thin (3 cm!) And low high enough, except at the joint. I feel that aspiration is a little more consistent with the standard brush. On tiles and parquet, it behave well and does well the job. The central joint is practical enough to reach the bottom of furniture / beds easily.

To summarize, I would say
Qualities:
- Effective
- Very light
- Pretty flat
- Very handy (the joint is great) => Ideal for pass under furniture or in corners that required previously going through the nozzle.
- Supplied with an adapter for vacuum cleaners baalais (I think)

Faults:
- Astounding during the first use (by weight and fineness)
- Interest of such a brush may be limited for many users.
- No "stopper" for attaching the tube to the vacuum cleaner, as the standard brush. (It may seem silly but for me it is annoying and makes me a peeu to use it only for areas inaccessible to the standard brush ...)
- Price high hair.

I have quite hesitated between 3 and 4 stars and have floundered for the highest note because even if some item annoy me (rhaaaaaa this tab ...), when I use it, it's still pretty darn convenient.
