Recently purchased product, tested on some cylinders with corks "long natural" caps "agglomerated" and finally "synthetic", what is striking at first glance it is rather successful design of this product, I regret cons finish not up to this apparent screw at the other end of the logo is round head (she keeps the engine block at the transparent part) is unacceptable in this type of product and the price: So little do better! Efficiency is the rendezvous each plug is removed easily small flat on synthetic or corkscrew seems forced, I am more reserved, however, for the spin (interchangeable) its base is square section (for training) and is not maintained satisfactorily at it too much freedom (given its length) and two caps these were drilled in the center but the spin was drilled through the cap causing the rupture of a plug portion found in the bottle.
The auger is broken for no apparent reason on a cork stopper (can be a lack of it), the commercial service of flavors Peugeot (effective) to me changed without problems: bravo.
To: sober design, efficiency.
Against: lack of attention to the spin stand, the screw keeps (round head) too visible on a product of this price.
Conclusion: good product, effective but too expensive the price / quality ratio is not at the rendezvous.
