Don't buy
Weed eater first tank was great second hard to start third tank you might get it to start. Trimmer head has a hard time feeding string out and a lot of black oil pouring out of muffler. Now after looking at the reviews I wish I had read them first all the same problem. Included picture of exhaust this is just three tank full using premix gas Home depot carries

    Will start 25% of the time
    Bought this new in May 2021 and have only been able to use 25% of the time. The other times it will not start. I only use the pre mixed fuel purchased from Home Depot and I follow the instructions for starting that is given in the manual. I am very dissatisfied with the quality of this trimmer

        I Always buy ECHO but this one's limon...
        I love the srm 225 trimmers and have been buying them for the past 15 years starting with the grey model. Bought a new one this past March. It runs great just like all the ones I've had in the past. But echo has changed something in the motor for emissions or an O-ring didn't seat properly. It dumps oil out of exhaust bad and not just a little it's everywhere. Echo tells me I must run it at full throttle 100% of the time to avoid this (was never an issue on any of the other echos I've owned) even with running it full throttle it still dumps oil everywhere. Echo told me to take it to a service tech but he said the same thing and said it's a problem with all the new echos. Not happy with it and after all these years buying Echo I might just make the switch to Stihl for my next trimmer. I know this is not a gas/Oil mix issue as I currently I own two echo blowers and another srm225 and the exhaust is clean on all of them using the same mix.

        Plenty of power little to no vibration
        Purchased March 20 2021, used the echo red armor 50:1 mix and it fires right up with little to no smoke. I have 8 hours on this srm-225. It’s light enough for this this old Man, little to no vibration and cranks every time in the 3rd pull using the prime choke pull method. The only two things I don’t like is the black funk that leaks out of the muffler, (yes I run it WOT 90% of the time) and this one is probably user error but I was trimming tonight and I kept hitting the run/off switch and it would just shut down.

        My first Echo purchase....very disappointing
        The pull string to start broke after one year. Contacted Home Depot and they don't carry the part. I "upgraded" to this after my Craftsman went on me, but that was after 10+ years of service. Didn't even get one hurricane season out of this overpriced joke. I will never spend the extra for an Echo product again, not going to get me twice.

          This is a work horse.
          I love reviews. This trimmer has over 6000. So I got one. I have two acres about 30 trees, outbuilding, garage, and coop. Takes about an hour to weed wack everything. Not once did it stop, slow down, or give in. It is a work horse. I do need a strap for it but only a preference for straighter lines. Not to heavy.
