I found the Ryobi 18V ONE+ cordless 50cm hedge trimmer a very easy hedge trimmer to use. Otherwise, you might find you are more comfortable with a smaller sized hedge trimmer or a wired model that does not carry the weight of a battery. I would recommend that you try holding one before you buy it and see if it is something you are happy to work with.
While it's similar in weight to the other manufacturers’ models of the same size, I do think at 2.8kg, it is a relatively heavy piece of equipment to hold for a prolonged period. Bearing in mind that some hedges are higher than others, this is something to take into account. Over time, I noticed that the weight of the machine became a bit of an issue, especially for our smaller-framed tester. When compared against a Stihl HSA 45, I did notice that the trimmer sounded a bit less smooth, but this was simply an observation rather than a criticism. In terms of noise level, I found the Ryobi 18V ONE+ cordless 50cm hedge trimmer to be comparable to other hedge trimmers of a similar size.
