GTS4QL-L 4QL Gas Powered 26.5CC Straight Shaft Grass Trimmer
Nice, lightweight trimmer
Cam99
I decided to buy this brand again after I bought the Senix blower back in the fall. I really liked the blower and the trimmer has been great too. Easy to use and lightweight.
CSX5-M-0 X5 Cordless 58V Chain Saw
It works well, and does the job
John from PGH
I bought the Senix chain saw after I bought their pole saw, which I have reviewed with the same headline. Bottom line, its runs and cuts nicely, and has a nice price point. It also uses the same battery as the pole saw, so I have a back up for both.

Good mower for the price. Overgrown yard no biggie. Bags a little small, but did a big yard on one charge easily.

I love the fact it doesn't need fuel mix. Just straight up gasoline. Plenty of umph and starts with ease every time even on cold days. Garage, driveway, back yard, truck bed...all get the blast and results are immediate!

So far so good with this battery. I use it on the Senix battery operated pole saw. The charge seems to last quite a while.
