Far too expensive for the quality

I ordered the opener because often not the Swatch watches can be opened with coins, especially if the seal sticks to the battery cover. Man commits a great risk if you too handled with the coin to scratch the lid or to over-tighten. Often Does a 20 cent piece, but not always.
Therefore, I ordered the "professional tool" to protect my watch before the battery leakage.

Delivery 1 went back by return mail.
Shortcomings:
1) surface in addition to the collection was not smooth and even
2) survey itself was worn / broken, so I did not try to open a clock so that at one point.
3) the metal pin is not exactly positioned in the handle so that you do not have optimal leverage for screwing.

Replacement sought new tool tested, lack Nr. 3 also even with this tool.
The rest is OK.

At this price one can expect a higher quality. It seems that the opener be custom built, so you have to live with the handmade defects, otherwise I can not explain it.

However, since this is the only provider, remains a no other choice.

How to say always - a 1A exchange settlement Amazon.
