Be forewarned: This IS an RTA piece of furniture. If you do not know what RTA is, you might not want to buy it. If you have done a few Ready To Assemble (RTA) pieces of furniture--SUCCESSFULLY--then there is nothing about this that is any more challenging. From start to finish, I had this together in two hours. That time included unboxing and inventorying the parts. That does not include the time that I spent on one of the sliders. Its bearings came out and I needed to put it back together. More on that in a minute.If you have not done RTA before, it is vitally important that you inventory and sort all of your parts BEFORE you assemble anything. You might be missing parts and it really stinks to be half-way through a project and have to stop and order the missing part from the vendor. I've never had to pay for a missing part, but it does mean that the piece of furniture sits there half-done for a few days. That's a bummer. So inventory first, before you start. Also, an organized pile of parts makes the assembly process so much easier.The second tip: If you don't have one, go get a power screw driver WITH an adjustable clutch mechanism. DO NOT WASTE your money on something that doesn't have a clutch. Your assembly will go so much quicker with the power screwdriver and your wrist will thank you. The clutch prevents you from over tightening the screws, which prevents the stripping out of the wood screw holes. A solid assembly does not require an immense amount of torque be applied to each screw.Third tip: The goal is to set the clutch so that the screw head makes contact with the surface, snug, and the clutch releases. Start the clutch at its lowest setting and work your way up to the right setting. The setting will likely change with different sizes of screws.Here's a comparison of a screw driver without a clutch to one with a clutch. Both are available, here on Amazon:BLACK+DECKER LI2000 3.6-Volt 3-Position Rechargeable Screwdriver -- This one does not have a clutch. At least it is not listed as a feature. Although it looks like it has a clutch, it is actually a switch for locking the spindle so that you can use the screwdriver in manual mode. I would not suggest this one for this project.Black & Decker PD600 Pivot Plus 6-Volt Nicad Cordless Screwdriver with Articulating Head -- This one does have a clutch. It is listed as part of the product's features. You can also see that the ring around the bit is numbered. That is a good indicator that this one has a clutch. It is only a few more dollars and for the extra money, it will help prevent the stripping of the screw holes in the wood.If you want to look at other options, I did a search on "cordless screwdriver clutch" or "battery screwdriver clutch".If you have a few bucks to spend, I'd suggest looking at: "DEWALT DCF680N1 8V Gyroscopic Screwdriver". It has two options: one or two batteries. For ten more dollars, get the two battery option. Nothing beats having a second battery, that is fully charged.When you are assembling the cabinet, make sure that you carefully note the orientation of the main cabinet's side panels (which one is the left panel, and which is right). Make sure that you are putting them on the correct side. They can be accidentally reversed and if that is done, you will find out later that the half of the drawer sliders, that attach to the inside of the panels, will not match up with the other half of the sliders, that are attached to the sides of the drawers. I was not paying attention and put the panels in upside down. So when I went to put the drawers in, the sliders would not match up. I literally had to switch the two panels around and then the drawers fit it just right. The rest of the kit cannot be accidentally reversed.Once the cabinet was assembled, I put the drawers in. The top three went in without a hitch. For whatever reason, the bottom one decided to be a pain in the rump and the ball bearings came out of one of the sliders. I took it apart by taking the rubber stop off of the end that is attached to the side of the cabinet. With the rubber stop removed, I was able to slide back in the extension, adding ball bearings to each of the holes, just before they were slid back in. If you don't have the patience, you might just contact the vendor and have a new slider sent out. Once all of the ball bearings were reinstalled, I reinstalled the rubber stop and for whatever reason, the drawer just slide right in like the other three. VOILA! Job completed.It is a nice looking cabinet. I am able to use the traditional green hanging folders, using the hardware that is built into the drawers. I just measured one of the drawers and it is 14-1/2" in depth (front to rear), inside measurement. So you might be able to buy a legal hanging rack that could fit, but it would be tight. This cabinet is definitely set up for the use of hanging folders that hold 8-1/2" x 11" though. So all you need to buy are the hanging folders.I really like the look of it. The dark finish and handles match other pieces of furniture that I have. Once it is all assembled, it fells very solid. If you have small kids, I would strongly suggest attaching it to the wall using the bracket that is provided in the kit. I could see where this could tip over if a child is climbing on it. The other option: buy two and attach them together in the back.So I do feel comfortable with strongly recommending this product. It is not any more difficult to assemble than any of the other RTA furniture pieces that I have worked on in the past. It uses the same assembly procedures as other manufacturers. So the process will feel very familiar. If you don't have a battery powered screw driver WITH A CLUTCH, buy one as part of this purchase. You will use it on so many other things around the house. You'll wonder why you did not get one sooner. And it makes assembling this project so much easier.Good luck!UPDATE 2018 11 25:I was rearranging my office and had to move the filling cabinet. There's a trick to removing and reinstalling the drawers. There is a small black tab, inside of each track. As you face the cabinet, pull out the drawer and look on the right side. The black tab is pushed DOWN. On the left side, it is pushed UP. This action releases the drawer lock so that it can slide all of the way out. (See pictures of the left side.)
