Their products typically operate with an efficiency of around 90%, which may be sufficient for less energy-intensive applications. Microtek also offers a 2-year warranty, appealing to budget-conscious consumers.

<pWhile Microtek's lower price point is attractive, the trade-off is a compromise on efficiency and service availability.
