With a 5AH battery, it lasts long enough to get the job done, but it drains the battery within 10-15 minutes of continuous use. So don't expect to be able to use it and have the battery remain charged for the next day. It is perfect for electrical work, for junction boxes/switches/panels/drilling/everything.

It is also very useful for household use, but if you use it extensively, it will drain the battery. However, it lasts long enough to do whatever you need.

It is not as powerful as an air compressor obviously, but it gets the job done. For example, for dusting off the PC/keyboard... and in general, for cleaning up dust/particles/pebbles/and the like... it cleans them up quickly. And it's great for blowing air. Overall, it is versatile and makes your life easier.

It makes quite a bit of noise like all these devices. And it is quite heavy with a 5AH battery, and the trigger becomes tiring to press after a while, but at least it has the LOCK function so you don't have to hold it down. I recommend putting a little oil on the LOCK to reduce the sound of the spring.

The trigger also adjusts the speed, in addition to the 3 speed settings.

The motor is not brushless, which makes it heavier and weaker and consumes more battery.

The suction comes from the left side of the blower, so sometimes it accidentally sucks in your shirt (when you hold it in your right hand), but it's a minor issue, it doesn't change anything.

Also, I believe you can use it for suction as well, because all the attachments fit on the sides (without locking, of course), it most likely works, but it might be a bit risky.

UPDATE1: It does suction, but the problem is that the attachment doesn't lock on the sides, so it comes off if you press it a little where you're suctioning.

UPDATE2: You can unscrew a few screws on the sides to open it and clean it, but I don't know if that voids the warranty. Also, be careful not to unscrew the fan because I unscrewed it for cleaning and when I put it back exactly as it was, it started pulsating like a heartbeat when I used it... and I've tried taking it out and putting it back in with slightly different methods (tightening the screw/positioning the wheel) but it still pulsates when I use it. Now at least it doesn't do it constantly... but especially when I use it for a while at full power, it does it. So it's not worth removing the fan. It seems like the installation needs to be done perfectly to avoid pulsating. The wheels need to be in a specific position, and the screw needs a specific tightening. So don't touch it at all if it's not necessary.

UPDATE3: I replaced the wheels with different ones and it doesn't do it now. So the wheels were the problem.
