I purchased this horizontal pearl drill about 7 months ago...
At the time I bought it, I also decided to buy extra drill bits - 100 each of 0.7mm, 0.8mm and 0.9mm bits, and 50 of each 1.2mm, 1.5mm, 1.7mm, 2.0mm and 2.5mmbits. Personally, I LOVE this pearl drill; it's solid and accurate. My total cost, including shipping was $275 USD...plus I had to buy a converter to work with the electricity here in Canada...but that was only an additional $25 USD.
The drill is solid, weighing around 5kg, super easy to use and hasn't given me any problems with drilling freshwater, tahitian or akoya pearls.
However, the pearl drill bits do not work at all for stones.
