Rated 2.3 out of 5 by 421 reviewers.
Rated 1.0 out of 5.0 by Inconsistent Unit works well when it's running. The problem is getting it running. It is difficult to start at the best of times, but after a while become impossible to start. Idling function ceased working a long time ago. Lots of power, when it does run, but I am not interested in woking up to a coronary event to get it going. June 4, 2015

Rated 5.0 out of 5.0 by Light Weight & Lots of Power I found my Hasqvana 125R Trimmer c/w blade too large and heavy. After reviewing my options I selected the Riobi Power Head and Trimmer attachment because of size,weight and price. The interchangebale attachments has a great advantage. Primary use is at the cottage. I followed the gas mixing instructions to the letter, carefully measuring both gas and oil. The starting instructions must also be followed to the letter - as detailed in special "Engine Starting Procedure" sheet included with manual. Using the above instructions my trimmer started first attempt and every time after both during and between use. I have now used it about six times with great results. Great power to handle most very tall grasses and weeds. I did get into truble with berry canes - having to replace the trimmer lines. The trimmer line attachment method makes it extremley easy to replace. Overall a 5 STAR product! Highly recommended for home or cottage use in heavy grass and weeds. August 20, 2011
Rated 4.0 out of 5.0 by Lots of power This machine surprised me with the power and with the brush cutter attachment, it made short work of an otherwise big job. April 25, 2011
Rated 2.0 out of 5.0 by Not a good value I bought 2 in 3 1/3 years. If you get 2 seasons out of these consider it a bonus. No parts available very sensitive carb and fuel system. In order to get 2 seasons, you really have to know how to completey winterize if it will sit more that 2 months. Ethanol fuel eats the fuel system alive if not used. Better to step up to the Toro for a few bucks. Toro is more power and will last longer. 2 Ryobi machines cost me $200 to get 3 1/2 seasons. Toro machine was $129 for power head and all Ryobi attachments worked with it. Toro cost $129 for 4 years and still going I'm surprised Home Depot even still offers this product January 24, 2015
Rated 3.0 out of 5.0 by Good once carb adjusted When I first purchased this power head it had little power and did not like the throttle wide opened. I would have returned it had I not tossed the box it came in. Sounded like not getting enough fuel. I adjusted the the carb (I'm an auto technician). Now runs great. Factory adjustments should have never passed Ryobi's QC. Ryobi has done well for low level non comercial use tooling. I own many of their products along with Bosch (which is a superior product with a price). Unfortunately I would not recommend this power head right now to users who don’t want to make any adjustments straight out the box (they should not need too). June 17, 2012
Rated 1.0 out of 5.0 by Don't buy One word sums up this trimmer GARBAGE. Needed to replace my old Ryobi so I went to HD and picked a new Ryobi up. It would not stay running, took it back and exchanged it for the same model. Second one ran like a champ after two times using it. On the third time using it, it would not start no matter how many times I tried to pull it. Started my troubleshooting it had good spark and was getting fuel but would not start. I'm taking this one back also and getting a different brand. I purchased my first Ryobi and used it for 8 years guess this is what happens when you outsource to China, good brand names become junk. Won't buy another Ryobi anything again. June 3, 2012
Rated 3.0 out of 5.0 by Not good out of the box, but great after adjusting Out of the box the product worked for a little while and quickly became hard to start and would die if I gave it some gas. I was very frustrated with it - cleaned the carb, replaced the plastic pipes, filter and bulb with a kit, still no luck. This part is important- I was able to fix it by doing 2 things, 1: I had to adjust the hidden "high speed" ad "idle" screws. You can google this. I actually tapped them with a hacksaw so a normal screw driver could turn them. 2: I found the screws over the metal plate behind the actual motor would become loose which wouldn't allow for proper compression. I put some tacky glue (most prefer loctite) on the screws and tightened them down. With these 2 adjustments, the motor starts one the first or second pull and NEVER gives up. I think it's a tragic shame Ryobi released something which requires tuning after it's broken in, but I felt it was necessary for someone to post the method of correcting the problem. December 2, 2012
