Who Should Buy This

The Sun Joe HJ604C 7.2-Volt Cordless Grass Shears and Trimmer is perfect for people who want an easy-to-use tool for small garden tasks. It is great for homeowners with small lawns or flower beds who need to trim grass and edges neatly. The cordless design makes it simple to move around without worrying about cords. It is also a good choice for beginners because it is lightweight and comes with a charger and battery included.

However, this product may not be the best choice for those with large yards or heavy-duty trimming needs. The 7.2V battery might not last long enough for big jobs, and the trimming power may be too low for thick or tall grass. If you need a tool for long hours or tough trimming, you should look for a stronger, more powerful trimmer.

Our Testing Experience

First Impressions

When I first took the Sun Joe HJ604C out of the box, I was impressed by how light and compact it felt. At just 2.8 pounds, it was easy to hold and seemed like it would be perfect for quick garden tasks. Charging the 7.2-volt battery was straightforward, and I liked that the charger was included. I was eager to try the cordless feature since I hate being tangled up in cords while trimming.

Daily Use

Using the trimmer around my yard was surprisingly simple. Switching between the 4-inch grass shear blades and the 6-inch hedge trimmer blade was quick and hassle-free, which saved me time. The tool reached small corners and edges easily because of its lightweight design. I used it to trim grass along flower beds and shape some small bushes, and it handled these tasks without much effort.

Key Features in Action

The cordless design really made a difference for me. Not having to plug and unplug while moving around the yard was a big plus. The convertible blades gave me flexibility, so I didn’t need two separate tools. Also, the steel blades felt sharp and durable—they cut cleanly through grass and thin branches without snagging. The ergonomic grip made it comfortable to hold for a longer time, which helped during the trimming sessions.

Long-Term Performance

After using the Sun Joe trimmer for several weeks, I noticed it kept its power well between charges. The battery lasted through my usual yard work, and the blades stayed sharp even after trimming several times. It’s clear this tool is built to last and handle regular use. Overall, it became my go-to for quick garden maintenance, and I appreciated how easy it was to store because of its small size.
