Pros and cons

Pros

A dual-pen setup can reduce the need to change configurations between lining and shading, according to the listing.
Wireless operation allows movement without a cord attached to the pens.
The display and adjustable voltage provide visible operating information and a range of settings.

Cons

The stated 2–3-hour runtime is limited and depends on voltage and usage, so longer sessions may require a battery change or charging break.

Aggregate ratings are mixed, with a majority in the five-star category but a meaningful one-star share. The small rating base does not explain why customers rated the kit positively or negatively. Buyers should weigh that uncertainty against the listed wireless controls and short, usage-dependent runtime.
