Often fires two staples at once. I don't mean one after the other, I mean two staples come out at same time. On April 8th I posted the faulty unit (my opinion) on 48 hour delivery to them. I received the new item on the following Tuesday as promised. Obviously it is a bit soon to shower too much praise on it , but must say the stapler itself has a solid, robust feel about it, which to me is usually a good sign. When I have completed a larger project I will post my results here asap.

With the Tacwise nails and staples (Tacwise say you should only use their own brand with this) the gun breaks up the row of staples and nails that are in the unit, I guess from the vibration or impact. This means if you need to change sizes often you will end up with a big mess of small rows of staples/nails. I'm not sure if that's an issue with the machine or consumables, or both. In any case, I'm returning everything. PROFESSIONAL 2-IN-1 STAPLE/NAIL GUN– Heavy duty electric staple and nail gun supplied in a durable carry case, designed to bring power and high speed performance to professional soft, medium and hardwood fixing tasks Although retired, at this time I have a very busy schedule and the project on which the stapler will be used is way down the list so I prepared a small item to use it on just to test it. Great guns, I used 150 staples without one misfire or jam! Incredible, compared to the original machine. This product carries a full 1 year manufacturers warranty covering both faulty materials and faulty workmanship, it does not cover general wear and tear or damage, batteries, blades, bulbs and other consumables. In the unlikely event of a fault the item returned is subject to fair wear & tear and must not have been used beyond the scope of it's design.Fell to pieces on first use. It did about 150 nails and staples and then destroyed itself. It fired a nail sideways that went through the "non marking" head, and at the exact same time it broke off a huge metal piece from the side of the machine's head. This head is made from cast metal, very poor choice of material. I would guess cast iron or some cast alloy. Used this to make a trellis for climbing roses, using staples into softwood. It worked quite well but after about 30 staples it jammed. This continued until I finished the job, every 20 or 30 staples it jammed. This was over twelve months ago. I didn't use it for a few months then after six months or so used it again making a storage box with plywood. Same thing happened, roughly 2 dozen staples and jam! Still, with some patience managed to finish the box. Not usable with one hand if you want flush nails. Bounces away from the material and you end up with a non-flush nail/staple. This is to be expected I guess. for staples I suppose you could use it with one hand, as staples don't always have to be flush with the material.

VARIETY OF APPLICATIONS – Semi-professional pneumatic brad nailer for a range of second fix applications including furniture/woodwork assembly, cabinetry, skirting boards, sub-flooring, door frames, fencing, panelling as well as sauna, shed, cabin, caravan and boat manufacturing Also, it's possible to accidentally double fire, one after the other. There is no protection from pressing the trigger twice by accident. Leaves awful marks in the wood. When shooting nails it's a huge gash in the wood to the left side of the nail. When shooting staples it's only slightly visible, it often leaves a square shape with numbers, because there's raised numbers on the plastic "non marking" head. See photos attached. This is an issue even if you don't press down hard on the machine. Not always able to go through knots in wood, but this might depend on the staples used. I only used Tacwise staples and nails.

Today needed to staple a piece of mesh onto a wooden frame which was twenty inches by twenty. To put in forty staples took about an hour. Every third or fourth staple jammed! On two occasions three staples came out together.
