Quick verdict
A 2.7 pound one-hand pruning saw with a 6-inch bar, two 21V 2000 mAh packs, a spare chain and a full accessory kit in the box. It suits a gardener or older user cutting limbs under 4 inches who wants to skip the loppers and the gas saw. The caveat is that chain oiling is by hand from a bottle, and the 900W motor figure is a peak rating, not what two small packs sustain.
Strengths
- Stated weight of 2.7 pounds, genuinely one-handed
- Two 21V 2000 mAh packs and a charger in the box

Weaknesses
- No automatic oiler; chain is oiled by hand from a bottle
- Small 2000 mAh packs limit continuous cutting
- Chain pitch, gauge and charge time not stated
- Proprietary packs, not a mainstream battery platform

Who this saw is for
A six-inch mini chainsaw replaces the pruning saw and the loppers for limbs between one and four inches thick, the size that is too much for shears and too small to get a real chainsaw out for. The Seesii 6-inch kit is a light one-hand saw at a stated 2.7 pounds with two 21V batteries, pitched at gardeners, older users and anyone who cannot or would rather not swing a gas saw. It suits a lot with fruit trees, hedges that have grown into trees and a brush pile that needs cutting down to size for the bin.
This review is based on the maker’s published specifications and on recurring owner feedback. We have not run this product ourselves.
What you get
The kit is complete except for bar oil: the saw, two 21V 2000 mAh batteries, a charger, two chains with one pre-installed, an empty oil bottle, a pair of gloves, a nut driver and a screwdriver. The maker states a 900W motor, a chain speed up to 30 feet per second and a weight of 2.7 pounds. There is a double safety lock, a chain guard and what the maker calls a low-recoil design. The listing says the saw arrives assembled with the bar and chain fitted. Chain pitch and gauge are not stated, so buy replacement chains from the same seller.
Cutting performance
A 6-inch bar cuts limbs up to about 5 inches in one pass and a little more from both sides. The maker claims a 15 cm, roughly 6-inch, log in about seven seconds; treat that as a best case in soft green wood with a fresh chain. The 900W figure is a peak motor rating, not a sustained output: a 21V 2000 mAh pack holds about 42 watt-hours, which tells you the saw cannot draw anything like 900W for long. In the real job, owners of this class of saw describe quick, clean cuts in green limbs of 2 to 4 inches, slower progress in dry hardwood and a chain that dulls fast if it touches soil. The listing does not say whether the motor is brushless; its comparison with traditional motors suggests an upgrade, but the word brushless is absent, unlike on the Seesii 8-inch Flagship.
Runtime and batteries
Two 21V 2000 mAh packs are the small end of mini-saw batteries. The maker’s 80 to 100 minutes of continuous operation and 100 pieces of wood are figures for light intermittent pruning; cutting thicker limbs back to back, plan on considerably less per pack and swap to the second while the first charges. The listing mentions overload and temperature protection in the packs, which is worth having on a tool that stalls in a pinched cut. Charge time is not stated. These packs are specific to Seesii mini tools, not a mainstream platform.
Build, handling and ergonomics
At 2.7 pounds the saw is genuinely one-handed, which is the whole appeal: one hand steadies the limb, the other cuts. The double safety lock means two actions to start the chain, and the chain guard keeps chips off the fingers. There is no automatic oiler; the oil bottle in the kit is for dripping oil on the chain by hand every few cuts, and skipping that step is the main reason owners of mini saws burn out chains and bars early. Noise is low by chainsaw standards.
Living with it
Oil the chain before every session and every few minutes in use, check tension after the first cuts with the included nut driver, and keep the spare chain sharp. Store the packs charged and indoors. Seesii states a two-year after-sales service with replacement or refund rather than a repair network; keep the order details. Wear the gloves and eye protection, since a mini saw kicks back like a full-size one on a smaller scale.
Alternatives to Consider
The Seesii Flagship 8-inch brushless kit adds two inches of bar, bigger 4000 mAh packs, tool-free tensioning and an automatic oiler for owners who will use the saw often. The BLACK+DECKER 20V MAX 6-inch pruning chainsaw runs on a mainstream battery platform shared with drills and trimmers. The Milwaukee M12 FUEL Hatchet 6-inch is the premium choice with a brushless motor and an auto oiler, at several times the price.
Verdict
Buy the Seesii 6-inch kit if you want a very light one-hand saw for limbs under 4 inches, two packs in the box and a complete starter kit, and you will oil the chain by hand. Skip it if you cut often or cut hardwood, where a brushless 8-inch saw with an auto oiler is worth the extra, or if you already own a battery platform with a pruning saw in it.

Seesii 6-Inch Cordless Mini Chainsaw with Two 21V 2000 mAh Batteries, Two Chains and Charger FAQs
About 5 inches in a single pass with the 6-inch bar, and a little more from both sides. It is at its best on green limbs of 1 to 4 inches.
No. The kit includes an empty oil bottle for dripping bar oil on the chain by hand before and during use. Skipping that step is the main cause of early chain and bar wear on mini saws.
The maker states 80 to 100 minutes of continuous operation for the pair in light pruning. Each 21V 2000 mAh pack holds about 42 watt-hours, so plan on much less in back-to-back cuts through thick limbs.
It is designed for one-hand use with a double safety lock and chain guard. Keep the other hand clear of the bar, wear the gloves and eye protection, and expect kickback on a smaller scale than a full-size saw.
