I'm going to list issues for you.It jams up a lot, including the first day, first use, first shot.It will also misfire, because the nail rack is very poorly made.Sometimes I can get a good run of shots in, but only if I take the time to realign the pin strip, because the end closest to the hammer raises up, and when that happens the hammer either doesn't even touch the pin, or it folds it in half which requires disassembly and reasssembly to fix. (I have literally never had this problem with my Porter-Cable pneumatic pin gun, ever, and I have gone through 3 of them in my life. I wouldn't be surprised if I have shot hundreds of thousands of pins with them.)I was super disappointed, and even moreso after I gave the manual a good look over, and then every single problem they highlighted in the troubleshooting section happened in the first day.I have since bought the DeWalt cordless pin gun, and it works almost as good as a pneumatic. And it doesnt cost much more than this one did at regulat price. A difference I was willing to pay to have the gun work every time I pull the trigger.The feel of the gun isn't bad at all, and that is one of the things that is so upsetting about it all. It frels like a good tool and performs like garbage.As others of have said, the non mar tip is not on there very well, and it really doesn't do its job. The secondary one works far better.I woukd also like to say that I was shooting soft wood with all of those issues, so you can bet your bottom dollar that I would never even consider using this tool on hard woods, like exoensive cabinets and trims that match, unless of course I had plenty of time to spend an entire day repairing all the problems it caused by the continuous malfunctions.It sucks. It really does. Anyone who is saying otherwise either has never used a working pin gun, or they got the one gun in a thousand that works like it should. The bad reviews speak volumes. They're all correct. I am very disappointed in this product.Having to constantly reallign the pin strips in the rack is super irritating.Someone else mentioned the fact that you cannot stack strips either. That is true for the most part, so consider the fact that you are going to have a 10% loss on every strip, because 20 left means you are out. (The Porter-Cable pneumatic will shoot until it is completely empty, and then it will not even dry fire.)If you used this gun daily, you will quickly eat the savings on a good price point with unusable pin strips.It seems to do a little better with longer pins as far as them staying in the rack straight, but it still will not shoot the loner pins that the Porter-Cable does. So you are limited in that respect as well.I have been waitng for the cordless pin nailers to come out forever so I could lose the compressor and hose like so many others have claimed as well. This gun is not it. If you like to be annoyed, it is the perfect gun. If you want production and ease of use, buy something else.This gun is definitely not worth the aggravation it causes. In fact, I would rather untangle an improperly rolled PVC airhose on the coldest day in the dead of winter, before I ever use this gun again.I really hope all of you get to read my review, because it was written with matter of fact honestly from a seasoned and skilled tradesman. There are far better products on the market, and they are worth every penny.Good luck shopping for a gun that works. The Ms and DWs are far superior.Update: 2 months after purchase.I have narrowed down any nail related issue and haven't had many problems with missfiring or breaking nail racks since. When loading nails you have to be very careful to push the nails to the magazine bottom so the nail guide properly goes over the top of the nails and holds them in place. Also battery lasts a long time. With intermittent use, the battery lasts a few days.Upping my rating.Prior review:I've been wanting a cordless micro pin nailer for awhile now to complete my cordless nailer set. Was holding out for Dewalt but they still don't make a cordless micro pin nailer. So I decided to go with this one.I'm using the larger 3amp hr battery. The battery life is great, plenty of shots on a charge, like hours. The gun revs up and shoots pretty quick, much faster than the larger brad or trim nailers. It is also pretty quiet.The convenience of not having to drag a air hose or compressor around it great. I've been using it to shoot on Africa mahogany trim, which isn't the hardest lumber but I haven't had any issues shooting threw it.I've only had a few nail jams, which were from using to long of nails ... this job has drywall glued to the concrete block, yeah wtf.When you do have a nail jam it can be hard to tell right away. The gun will appear to fire as normal but be shooting blanks.Also fires normal when your out of nails all together.Another issue I've had is the nail racks breaking in half and the back section sliding over the front, pinching both so they don't feed forward properly. This is with on brand nails also. This doesn't happen often. But when you get low on nails and go to add another rack, having now two sections in the gun can create the same issue.I hear cheap nails bend more, they suggest you use brand name nails only (harbor freight = cheaper / softer metal = more nail jambs).I would buy this gun again and I am mostly satisfied. 4/5 stars.Not a bad gun. I was a little hesitant to make the purchase based on some bad reviews, and after a few thousand nails I can say they weren't entirely wrong. My first gun started jamming after the first 1000 shots. I talked to some great guys in the Metabo factory service department who were willing to admit the tool can be a little finicky. It seems it demands to be kept uncommonly clean. Their recommendation was to clean it with a fast drying, electronics style solvent and lube it up with a silicon based lubricant. Apparently the glue that holds the pins together builds up over time in the magazine and keeps the fasteners from advancing properly. This crud does not have to be readily apparent from a visual inspection in order to cause problems. That gun was still under warranty, so I returned it just to be safe, but I now have a go bag with the suggested cleaning products. I'll admit that a tool that requires that kind of cleanliness is not exactly ideal on a job site, but I wanted to keep to one battery system and their other guns are superb.Update: my second gun had the same issue after shooting a fair amount of nails. This time I was prepared with my solvent and lube; the combination worked like a charm, and oddly enough I've shot even more nails afterwards without any further issue.Awful Pin nailer, misfire on first use, awful nail removal when stalling.Just don’t purchase it,Que dire a part que cette outil est parfait, très efficace ne manque jamais un clou et durer de vie de la batterie de 3ah plus que suffisante . Metabo HPT est vraiment supérieur en frais d'efficacité et de durabilité ainsi que de qualité que dewalt et makita. J'était un vendu dewalt, j'ai plus de 20 appareil sans fil et 23 batterie de marque dewalt, je suis charpentier menuisier de métier , j'peux vous dire que je n'aurais acheter aucun dewalt si j'aurais connu metabo HPT avant. C'est dommage a dire mais dewalr est très correct pour un bricoleur du dimanche pas pour un homme de métier ?su bateria de 3 ah le da una gran potencia pero me sorprende lo silencioso de su disparo. los pines de 23ga. sin cabeza dejan una perforación casi imperceptible. yo ya uso desde hace tiempo otra clavadora de bateria con 18ga. y por eso no dudé en obtener esta metabo y estoy muy satisfecho con la compra. su precio, por otra parte es excelente, considerando su utilidad. Es una herramienta que se utiliza en todas las etapas de un proyecto.Very pleased with the performance and efficiency. The gun is so much lighter than a battery brad nailer and quiet to boot with strip loads from a small carry box of 10,000 pin nails. Painter is impressed that the holes are so tiny he just paints over without Alex spot filler. This tool is a must purchase for every trim carpenter!I purchased this nailer thinking I would only use it for service or when it was not convenient to pull out my air compressor and hose. After using this nailer for a couple months now I'm finding that I haven't used my air pin nailer since I got my new cordless nailer. This is a great nailer that has a solid feel and a very nice grip. This is a must have tool! I am so happy with my purchase that I've purchased more of these nailers for my employees.
