The Echo eForce 21 inch Battery and Charger Lawn Mower is a great product with a variety of cutting heights and features. It is well built and comes with excellent quality construction, but the 5.0-amp hour battery is not something most people care about. It is also easy to use and adjust, and the handle is large and easy to use. However, the battery gauge is not very accurate and the mower can be noisy while mowing.
