GreatHunt @rtytf | Cheap But Powerful 💪

Pros:
The first excess brought by "SonarPen" is the cheap price (About $ 35 for investors, and $ 45 for retail). This price is quite cheap by the difference of almost $ 50 with other products.

In addition to cheap, SonarPen also has a high sensitivity, so the use (especially for drawing) can be more leverage.

The next advantage is that SonarPen does not need to be refilled and does not require a battery. This is a perfect innovation right now!

Cons:
None. This product I really need.
