Summary:
Very impressed at first use. Very disappointed that it's in the shop for repairs after only two or three hours of use. Very disappointed that the shop told me that it would be at least 10 days before they could get to work on my KM 90 because they are that far behind on repairs. If they actually fix it and it runs, consistently, like it did when I first fired it up, I would give it a 10 out of 10. I have read a few forums on this subject and have found out that there are a lot of people having the same problems with this motor.

Strengths:
Power, multiple tools, looks cool, fuel efficient.

Weaknesses:
Used it for two hours before it broke. At first it was very easy to start. After a couple of uses it became more difficult to start. The last time I used it, it started easy when it was cold, but I had to crank and crank and crank after shutting it down to change from trimmer to blower. After I finally got it to start, it sputtered and died. Cranked and cranked and cranked and it started again. Had to feather the throttle trigger to keep it running. Once I got it up to max RPM, it ran okay, but I could tell something still wasn't right. Rather than shut it off while I moved a few things off the sidewalk so I could blow it off, I decided to let it sit and idle. It idled okay for a couple of minutes and then it shut off. After that it wouldn't start again.

Summary:
I love mine, and if you are a professional, or a homeowner, I would say this is the best product you could buy. This product is expensive, but well worth the money!

Strengths:
POWERFUL- no need to buy the larger motors. I have used the trimmer, edger, pruner, and hedge-trimmer. I also bought the 37" extension, which I found to be very handy. I was impressed with all of them. Believe it or not, the blower actually works great. I was a bit skeptical of the blower, because I felt it looked like a gimmick tool. All of the attachments work great, and this KM90 really has more than enough power. I would absolutely recommend it to anyone.

Weaknesses:
None that I have found.

Summary:
It is really a cause of cnroecn that HAL has only screwdriver technology and they can only assemble under license of all imported components.They cannot evan assemble imported parts on their own.Basic trainer is a little more advanced than second world war fighters.It was 70 years ago P-51 mustang was designed and with feedback from the test pilots the engine was changed to spitfire Merlin engine and a world beater decisive weapon was born which changed the course of the war. The whole designing process took 19 months and in that time frame it was cutting edge technology and never ever tried.HAL badly failed in that effort with years of work , needless to say they were to fit it with some videshi engine as designing a turboprop engine is beyond the imagination of HAL.IJT trainer is showing no progress with a poor decision of choice of engine AL 55 which is still experimental and unreliable and they should have selected Honeywell F 125 engine which is very reliable like GE 404 or GE 414 and designed the trainer around it.Designing the body is not very difficult and time consuming.This technology development should not have taken this long.It would have been a good decision had this project being given to some private company that takes pride in completing a prestigious project.It is out question that HAL would design the engine and few vital components as they are going to pick it up from the market.Is it worth now to keep those people in job who have not delivered anything in name of IJT.How can these people justify their job by not delivering anything workable which is reliable. I am happy about Tejas that the engine selection was a right decision and that is why so far not a single tejas has come down.Tejas needs lot lot of high end technology and it is difficult and time consuming but i cannot justify the delay in BASIC TRAINER as well as IJT as these are not that time consuming and not that complex technologies and selection of PILATUS clearly shows HAL missed the bus on basic trainer and i wont be surprised if IAF selects another videshi IJT. as HAL could not produce one.I feel angry with the degree of incompetence and lack of accountability.TIMBAKTOO
