There are advantages to buying more than one cordless tool from the same manufacturer - the batteries are interchangeable so if one or two of your batteries die before their time you have spares and spare chargers which let you charge several packs at one time. I have the Baokaler weed trimmer, mini-chain saw and this mini-blower all using the same 21 volt batteries. I checked and could find no replacement batteries from this seller so the fact that I now have 5 of their batteries avoids trouble later. The blower battery is the heaviest of the three types provided by Baokaler, it is rated as 4 AH. This blower is compact with a short nozzle and may be better for cleaning out sawdust in a workshop or similar close quarters jobs. I took it out to my driveway and patio covered in leaves and it does work as long as you bend and stay close to the ground as it blows - and this was while using a half charged battery. I rummaged through my vacuum parts and found a 16 inch extension wand that fits over the end of the blower nozzle so now the wand is about two feet long instead of 8 inches, a big improvement that lets you sweep over a larger area without moving or bending as much. I am skeptical of this thing's ability to be used as a vacuum cleaner but If I had a soaked carpet or a mess of sawdust I might try it. A short vac hose, crevice and wet nozzles are included. This is a light weight tool so it might make it easier to blow out your gutters while up on a ladder. The noise level is tame compared to most leaf blowers and there is no high pitched noise, it sounds more like an old vacuum cleaner.
