High quality professional tools
When my Bosch 18-volt Lithium-Ion Cordless Drill/Driver and Impact Driver Combo Kit arrived the two 4.0Ah lithium-ion FatPack batteries were partially charged. One out of three battery indicator lights was lit. A trip to the included charger got them fully charged in under a half-hour each.
The 1/2" hammer-drill ships with a variable position detachable side handle and an adjustable depth limiting rod. The 1/4" impact driver ships with a removable belt clip and a double-ended #2 Phillips bit

which stores neatly at the rear of the driver. Also included is an 18 volt charger and an equipment bag for easy portability of the complete set. There are seperate instruction manuals for the drill, impact driver and charger.
If you're familiar with LI batteries you'll know that unlike NiCads they don't lose power as the battery drains, they just suddenly quit. I won't buy anything that comes with NiCad batteries anymore, lithium-ion is the only way to go, they are far superior. I've read many negative reviews relating to battery operated tools and almost all of them refer to poor battery performance. I think the biggest problem is that users are treating their lithium-ion batteries as they were taught to care for their NiCad batteries. They're two different animals and need to be cared for differently. I found the following use and care tips on the Internet.
1: Keep your batteries at room temperature. That means between 68 and 77 degrees F. The worst thing that can happen to a lithium-ion battery is to have a full charge and be subjected to elevated temperatures. So don't leave your battery in your car if it's hot out. Heat is by far the largest factor when it comes to reducing lithium-ion battery life.
2: Avoid charging a hot battery. Whether from heavy usage or hot storage it's best to allow the battery to cool down before attempting to charge it. I normally try to cycle three batteries during the work day. One in the tool, one cooling down and one on the charger.
3: Allow partial discharges and avoid full ones (usually). We were taught to run our NiCads all the way down before giving them a full charge. With lithium-ions it's better to recharge before the battery is exhausted and partial charges are no problem since theseunlike NiCads, don't have a memory.
4: Avoid completely discharging lithium-ion batteries. It's time to cool down and then recharge them when you detect the battery is providing less than optimal performance.
5: For extended storage, discharge a lithium-ion battery to about 40 - 50 percent and store it in a cool place. Storing a battery in the discharged state can push it to the point where it won't recharge, and storing a battery fully charged can shorten its life.
I have many lithium-ion powered tools and other devices and as of yet I haven't been disappointed with battery performance. I attribute this to proper care.
I've only owner this kit for a short time so I haven't had the chance to torture test it yet but based on the performance of my other Bosch tools and the excellent 5 star reviews for this kit I don't anticipate any problems. These Bosch tools are very well made and will take a beating, trust me I know from experience. With a PROVANTAGE signup registration the tools are warranted for 3 years and the batteries for 2.

Solid, high quality hammer drill and impact driver
I've previously used DeWalt 20V Max cordless tools, but a friend always raves about his Bosch tools, so I decided to try this kit.
In short, both the Bosch Hammer Drill and Impact Driver included in this kit are very solid, well made, and work great. The fit and finish and build quality are excellent. No rough edges, seams, rattles, flex, or any issues that I could find.
The design of both drivers is very good, with comfortable rubberized grip areas, well placed trigger, and easy to reach

forward / reverse switch.
This kit includes the larger "Fat Pack" 4.0 Ah batteries, which is a nice addition for the kit, and I suspect will be valuable to keep the large hammer drill running longer.
The trigger / motor response on both drivers is very smooth--it's very easy to feather the trigger to control the speed.
I only have a few minor criticisms:
1. The impact driver is about 6 ounces heavier than my DeWalt impact driver. The additional weight is noticeable, so if weight is a concern, or if you are carrying the impact driver on a belt all day, this may be a consideration.
2. The hammer drill is a full 5 pounds. It is a beast. While the large size and heavy weight does make it very smooth and steady when drilling wood, and likely helps when using the hammer drill feature, I would only recommend this larger "Brute Tough" hammer drill model if you know that you are going to regularly need a hammer drill. If you only use hammer drill occasionally, I would recommend checking out the smaller "Compact Tough" hammer drill. If you use hammer drills rarely, I would go with the standard drill/driver and just buy a separate inexpensive hammer drill for that rare use. The 5 pound hammer drill is bulky and heavy, and isn't something I would want to use constantly on woodworking, framing, etc. where the hammer feature is not required.
3. The battery charger is the largest I've seen. It's larger than my DeWalt and Rigid chargers, and sounds like it is mostly hollow. If you have to take the charger to job sites, I suspect it will be annoyingly large. It does have an internal fan, but I really wish they would work on making the chargers more compact. And just like every other charger I have seen, it does not have any option for wall mounting. So if you want to mount it in your shop or garage to save space, you'll have to make your own mounting solution.
Overall the Bosch drivers are excellent and certainly as good, if not slightly better in some respects, than my DeWalt cordless tools.
