I had an older version of SunJoe. It had a fixed battery that couldn't be removed according to SunJoe customer service so there was basically nothing that could be done since the mover doesn't take a charge anymore.However,that mower lasted me 3 good years so I felt a newer model with a removable battery that I could charge indoors would last me just as long or longer.My new SunJoe 24v-xz with 48voltsIt weighs less,the motor is more powerful,and comes with two batteries and a mulching feature which I love. I use to bag all the time but this makes my small yard with little grass and patches look fuller but neater when cutting it . I like it shorter using the 1 blade level. The grass is starting to grow back and fill in in empty spots and the mulching helps.I got a good deal on it and I love it especially the color.My only 4 issues with it is this:1. The entire body of the mower is plastic and I'm kind of rough with my mowers so I'm concerned it may get badly scratched or damaged . My yard wasn't kept by previous owner and the terrain is treacherous so there alot of debris, holes,and hills. When going over humps or tree roots it just feel fragile but so far so good.2. Handle bars . Ok these things seem like a light weight aluminum and I feel if I try hard enough I could bend the bars in half with my hands and I'm not a bulky guy. The bars rattle while mowing and I feel like I just have to be delicate with it.3. Turning. Maybe it's just my yard but it seems just turning around to make another pass over an area I just cut isn't a smooth transition. I think it's due to the wheels.4.plastic wheels, this maybe why it's difficult to turn.the wheels are hard and may contribute to the overall rattling and vibration of the mower while moving. I feel if the wheels where rubber or rubber coated it would move a lot better.Pros:1. Customer Service: This is the biggest pro and why I purchased it. I had a SunJoe before and was familiar with there CS and when trying to get a new one they were helpful.Not just helped but responded in real time. I corresponded with them via txt. This seems to be the best way to go for quick questions and assistance. Other companies I call, I wait and maybe someone picks up but with SunJoe I txt they responded quickly. Now you have to be willing to txt if not this may seem uncomfortable but trust me it's seemless.If I have trouble with my mower I feel I can reach someone that could help immediately.2. Lightweight: with the battery in it's still light enough for an elderly person to a young middle school girl to use.3. The motor seems twice as powerful as my last. Along with the blade it cuts my grass like hit knife through butter.4.Batteries can be charged indoor which can extend life of the battery. Also I can get an hour of cutting time with both batteries in plus have enough charge to use one of my batteries in my SunJoe weed eater. This lasted a good 30 min .4.the website doesn't say this but if you wanted to you can collapse the handle bars to fold allow you to store the mower in a up right position.it makes it compact for storage.I simply lose the green knobs on the side and it allows the bars it to fold.Overall, it's is very good for the price and what you get. I got it on sale and was able to buy a SunJoe weed trimmer (tool only) for under $300 before tax.If you have a flat lawn that has been well manicured in the past then this mower will be even better.The more level the yard ,the smoother the ride.My whole family is pleased and my neighbors love the colors.
