Metabo HPT MultiVolt Sliding Miter Saw

I ordered this miter saw and was excited about it , I set the saw to 45 degrees left then 45 degrees right it the 2 pieces together and they didn’t add up to 90 degrees . Metabo replaced it with another saw that is every bit the piece of garbage that I sent back , the left fence isn’t on the same plane as the right . I also bought a 23 gauge nailer that I tried to get my money back, it jammed frequently and doesn’t set the pins . Today the 18 gauge metabo was misfiring and now doesn’t set the nails, last week my Metabo 6 1/2” trim saw stopped working altogether , and my cordless metabo ra dom orbital sander switch is malfunctioning . All of these tools are maybe a year and a half old . I am so disappointed , I also bought the triple hammer 36 volt impact , so far love it also 36volt 1/2 “ drill , so far love it also the big sawzall so far love it also oscillating tool cuts slow compared to dewalt , also ac line for 36 multivolt plug , also the cordless compressor also the 4 gang charger and the 18 volt 3/8” drill , you would think customer service would be helpful ,not yet . I have been a carpenter for 40 years ,? I will never ever purchase another green tool and if you do after reading this , good luck , you’re going to need it
