Purchased this item recently, and used it to drive a variety of exterior/interior screws as well as to drill into wood. Very pleased with its performance and capabilities. Compared to other manufacturers' right angle offerings, this unit may be the best choice for a lot of people.
I needed to do some work in areas with very little overhead clearance, and was not relishing the thought of using either of my two angle adapters/converters to do the job (I have a variable-angle as well as a fixed 90-degree drill adapter). Both adapters are keyed (chucked), are very cumbersome when attached to a drill (requiring two hands to position), and the thought of using either contraption to drive screws without slipping and marring the work surface isn't pleasant.
When the Makita BTL061 arrived, I was pleased with its build quality, which is solid and bulletproof. The head casing is made of metal, and can rotate and lock at various positions (although then the trigger and led light will no longer be inline with the driver head). The unit will accept either the 1.5 or the 3.00 AH lithium ion battery packs (not all tools in the LXT series will accept both). The led light, which stays lit for ~10 seconds after trigger release, comes in very handy when you're working in dark corners or recessed areas. The unit was made in Japan, and came with a belt holder and one short double ended Phillips drive bit.
The business end is very compact, compared to the other right angle drill/drivers I've seen, and certainly more compact than my angle adapters. With appropriate low-clearance bits, this will allow the user to squeeze into much tighter spaces. Torque control is manual, but it's very controllable with the variable-speed trigger. Although it isn't rated to 1,300 in. lb. as my straight impact driver (also a Makita) this unit provided more than enough power to drive whatever fasteners I needed. In fact, the unit was so strong that it sheared off the head of a screw when I inadvertently hit a hardened burl in the wood (I had to core out the snapped screw, but that's another story).
Unless you anticipate doing way more drilling than driving, I'd recommend buying this unit rather than a right angle drill. With hexed drill bits, you can easily drill with this unit. It may not appear to be as precise but if you anchor the bit into the material slightly and start slowly you'll get the exact same results as with a dedicated drill. Conversely, if you try to drive a screw with a drill instead of an impact driver, you'll be prone to slippage/stripping, and you'll be extending more force and effort to get the job done. In other words, this impact driver will be more versatile than a plain drill/driver. I wish I had purchased the BTL061 right away rather than wasted $60+ on my two adapters (which I don't see using again).
In summary, the BTL061 is a very well built, versatile tool which I can recommend without any reservations. It really proves its worth in those instances where you need its right angle form factor, and I've used it in place of my normal impact driver at other times.
