The most useless chainsaw I have ever worked with. I have had it for a year and the mechanic has had it for 8 months. I have changed 2 carburetors and now I have it for the 3rd one, and it has been at the dealership for 2 months and now they tell me I will get it in mid-April. And until now they were telling me from Friday to Friday. 4 months in other words, to change the carburetor again. If the chainsaw has cut 15 tons of wood at most. With the last carburetor, I didn't even manage to cut 2 car loads of wood. And now they are even telling me that it's the gasoline's fault. And what about the other 3 chainsaws that I have nearby, why didn't they have any issues???? From the beginning, when it's cold, it starts right up on the first try, but if you turn it off and try to start it again, you have to pray to the Virgin Mary and go begging for it to start. As for the blade and the chain, they are useless from the first cut. After just 10 minutes of cutting, especially with hard wood, it tightens and turns with difficulty. It also has excessive fuel consumption and burns a lot of gasoline and chain oil because the pump keeps turning and spilling oil even when it's idling. I have worked with chainsaws and this one was worse than a Chinese one. Now I can't understand what's happening with those who say good things about it.

Owner of the Cs50s for less than a year. During this time, I have cut about 15m³ of wood (mostly fir and pine).

Let's start with the negatives. It is heavy for a beginner user. Also, the air filter gets clogged quite quickly and needs frequent cleaning.

Now onto the positives. The tool cuts perfectly for an amateur (maybe semi-professional) chainsaw. It starts easily as long as you follow the instructions and not your own instincts (like I did at the beginning). It forgives common mistakes made by beginners (incorrect chain placement, etc.). Also, since it is a subsidiary of Husqvarna, most spare parts are easy to find in the market and are of good quality. Those who have used Chinese chainsaws will understand the difference in the first use.

I only use branded oils and a fresh gasoline/oil mixture. I clean it after each use and so far it has not let me down. Some people have complained about the blade and chain, but I have had absolutely no problems with these two so far.

Overall, (for a 2-star rating) if I could, I would give it a sixth star. Fully satisfied!

I am the owner of this chainsaw for 1 year, and I am completely satisfied. I use it for hobby purposes, although sometimes it can be quite demanding. Its main use is for cutting tree trunks. In terms of construction, it is sturdy and made with quality materials, and its handle is quite comfortable.
Regarding fuel consumption, I believe that the OXYPower technology performs well, as it has slightly reduced consumption (I estimate around 20%) and lower emissions (as stated by the company, -60%), with no unpleasant odors from the exhaust gases.
The Soft Start for starting the chainsaw is satisfactory, as the resistance of the pull cord is negligible. The automatic reset switch is quite useful, as with a pull of the blue switch, it is ready to start. As for the engine, there is a possibility of it stalling when cold, but once it reaches operating temperature, I have no issues with its idle. The idle reset at operating temperature after maximum RPM is commendable and does not hold dangerously high RPMs.
The safety features work with great precision, and it has the right resistance to activate them.
I noticed that the chain oil consumption may be slightly higher than expected, as there is no option to adjust it from the oil pump, but I do not condemn it for this reason.
The air filter is easily accessible, and the CCS Air Filter System technology, along with the centrifugal force, prevents a large amount of dust from reaching the air filter.
I use it with Shell V-Power 98 gasoline and Castrol Power 1 Racing 2T oil, as well as STIHL Forest Plus chain oil. I always try to have a fuel mixture only for the day I will use it to ensure optimal lubrication of the engine and avoid storing any unused mixture.
In conclusion, I am completely satisfied with the chainsaw. I purchased it because of the technologies it offers, which tempted me and made it modern. The only downside is its weight after prolonged use, but other than that, I take care of it as much as I can. Time will judge my choice, but it is definitely an enticing option in the 50cc category, considering its price, for both hobby and semi-professional use.

DEFINITELY BLADE REPLACEMENT.
After a short period of use, the chain would come off and I couldn't figure out what was causing it. After some investigation, I found the problem: the blade was heating up to a point where it would "tighten" and block the chain. I realized this when I tried to rotate the chain by hand. Once I replaced the blade, everything worked fine. As for durability, only time will tell as it is a relatively new product.

UPDATE:
After replacing the blade and chain - not particularly expensive, I used it to cut logs ranging from 10-15 to about 40 centimeters thick. It works very well, but it requires full throttle and full immersion of the blade, even for smaller logs of 30 centimeters, otherwise it easily stalls and you have to restart the work. DEFINITELY A LITTLE ADJUSTMENT AND PROPER WARM-UP BEFORE USE.

Also, something I noticed is that the "clamp" next to the chain easily gets misaligned, as well as the safety angle piece at the bottom of the chain, and you need to be careful not to let either of them touch the chain.

However, it is powerful and doesn't seem to struggle, considering its engine size and the price. But I consider it a major FLAW that the blade needs to be replaced, which is an additional cost that you can't budget for before purchasing.

LATEST UPDATE AFTER EXTENSIVE USE:
It gave me a lot of trouble at the beginning due to a small adjustment needed in the carburetor's fuel supply screw, it was obviously clogging and unable to work properly. With a little tweaking (turning it right and left and testing), it works like a charm, it doesn't easily stall like before, and it doesn't lose power at low or high RPM.

CAUTION: All of the above until I needed replacement parts!!!!

It is VERY DIFFICULT to find replacement parts for the carburetor, and it costs about 80€ in Greece, in ONLY ONE store where I managed to find it. Comparatively, carburetors for Husqvarna cost half as much from what I've seen.

Finally, after taking it for maintenance at a store, I pointed out the possible need for hose and fuel filter replacement, and they assured me that "it's fine." I had a problem because I went to cut logs and I encountered this issue. And for some reason, the electronic part didn't seem to be getting power, so I replaced it and it presented the same problem, and I thought that the electronics were burning for some reason. When I contacted an official Husqvarna service, the problems were resolved.
