I have read the other reviews, and found that some may have bought this expecting it to be an all around screw gun.
This is NOT what it is. While yes it can put some screws in wood and what not, I feel this unit is built as a HIGH TECH / HIGH POWERED ELECTRIC SCREWDRIVER!
This is what I purchased it for. I am a field engineer and do a LOT of work on devices which may have 30 screws on the back cover, like 60 inch tvs.
In this capacity it does an OUTSTANDING job.
I did NOT buy this on Amazon, but at Home Depot. It was 39.00 there (Sorry Amazon!)
I would also note for all, the 1st one I got, the slip clutch did not work at all.
A 10 min drive back to H.D. resolved this issue and the second one worked perfectly.
While I love Amazon, I also must say getting it at H.D. allowed me for 7 dollars to get a 2 year bring it in and we will replace it warranty. That with a 12 dollar extra battery, taxes etc did come up to around 70 dollars, but a well spent amount of money.
I would strongly recommend this IF you need a VERY GOOD Electric Screwdriver, If you need a SCREW GUN Go buy an 18 volt Dewalt or something!

I've been looking for a powered screw driver. My issue has been that the powerful drivers are as large (or almost so) as a cordless drill; so, they've only been useful in situations where there is plenty of room. If you can find one small enough, they seem to fit but often don't have enough power to do the job. I've experienced both of these scenarios with past powered drivers, about 50% of the time.

While the Tek4 isn't the most powerful, it comes close do doing the job 80% of the time. It's small enough to fit in tight spaces, yet has a comfortable and ergonomic grip so you're not stripping out screw heads with every turn when you have to use some elbow grease to do the driving.

The device has plenty of torque and sticks with Ryobi's other designs of two settings for speed and an adjustable drag control. The forward reverse is easily switched with the driving hand so you don't have to let go of what you're holding with your other hand. Charging is relatively fast, and you can get plenty of work out of a single charge, but I'd buy an extra battery, JIC.

My only complaint is that in the ads I saw it stated "driver / drill." And effectively, it could be used as a drill; however, the chuck is a hex fitting for all the bits, so obviously you'd need a set of hex head drill bits or some sort of converter, which I've never seen. I haven't thoroughly investigated, but I'm not sure you can replace the chuck on the TEK4 with a drill chuck, but I'll look into it eventually.

Overall, I don't know how I did without this little guy for so long--I wish I would have had it in my toolbox years ago. I'd buy it again in a heartbeat.

This is the most complete and versatile low-cost battery screwdriver on the market. I got one as a gift a year ago and liked it so well I bought this one for my son, a computer professional. The torque feature is particularly excellent, and the battery life longer than most. I was searching for a backup battery, but the truth is, for around-the-house work, it's not needed.

So this exact same product is sold at the Home Depot for on 29.95 regular price. I love ryobi for the durability and quality. This power screw driver gets most any typical job done and it's small and not bulky. I recommend it but don't pay here

Great perfect tool bench screw driver small and compact. It has enough torque to put a 2in screw through 2x4 but ideally not designed for that but it did it. Am satisfied with its performance so far so good. I like the clutch option for taking off screws and putting screws back into plastic items without damaging or stripping things. I've drilled holes with it also and it does the job. If your looking for power and torque your not going to get from this buy an 18v or 20v bigger drill for small and convenient work this is perfect for me.

good purchase for the price. lacks power vs snap on but the price difference is massive. the battery load is a little cheesy with the screwcap but the charger and included bits are nice. i use this tool to remove bezels when i change out headlights to save me from carpal tunnel.

Great little driver, I use this for working on my rc cars and the 2 speed transmission and 24 position clutch is awesome. This tool icost significantly less at Home Depot though.

I purchased this screwdriver for my father. He absolutely loves it and uses it often. He's added it to his collection of "tools". This item was in great condition and actually arrived quicker than expected! I highly recommend this as it's very well made and excellent quality.
