Keep on cutting
This 4 1/2" saw is AWESOME. It works great for small projects. No need to bring out the big boy for those small projects. I feel the balance is on point once you add the battery. I do have the bigger batteries 6 AH and 9AH. I feel if you use the smaller battery, you might feel the saw tilt more on the saw side. Keep that in mind. Build solid and the motor rips though 2x6 boards with ease. Yes, I recommend

Great tool!
This has become my go to saw for most of my work. Easy to handle and has plenty of power. Its just able to cut two by material and is very easy to manage on plywood cuts on walls for example since its so light. I agree its looks a little weird at first but I have grown to use my "axe"

Incredibly versatile small saw
I love this saw . It's not that heavy, because of size its very versatile and quite hardly any noise to it with alot of power and torque for a battery operated saw. Feels very durable. Worst part about it.... is the Allen wrench they give you to change blade. It doesnt stay put, you will lose it because it keeps falling off and barely snaps into place. Easy to install blade and saw dust is thrown though moveable chute out of way really like that myself. This is kind of pricey though, so $$ wise not a great value, BUT the real VALUE is its easy to handle and work with part even in awkward positions. I have a 9 amp/hr battery hooked to it usually and in a whole day of use never made battery go dead. They also give you a ripping guide also. No matter I still recommend it though. These tools are proven to be durable

Dewalt tools are for women too.
This 4 inch circular saw has given me the freedom to make and fix projects multiple times. Being much lighter than a regular sized saw, it is functional, powerful, well built and fairly priced. I have used it to enclose cabinets, make shelving, make slates for my bed and plywood support for mattress. I can even cut thick boards by cutting part way and turning to cut the rest. The light is very helpful to increase accuracy. I have several Dewalt tools and prefer this brand.

One of My Most Used Tools
I already own a full size framing saw and even a mid size cordless circular saw, so I really thought I did not need this saw at all. I ended up buying it on a whim, thinking it might be handy for trimming some vinyl floor or perhaps doing small jobs around the house. Now it has become one of my most used tools. I've used it for drywall, plywood, fencing, flooring, and even an occasional 2x4. It is just a great light, versatile saw that requires no setup and cuts great. Unless I have a big cutting job to do, I'll always reach for this saw first. For example, recently I had some bad sections of decking to remove, but I did not want to replace the entire 12 foot deck boards because the screws are all shot, and I wanted to minimize damage to the joists. So I set this saw to the right depth and did a precise plunge cut over the joists, and then finished the cut with an oscillating tool. Then I used the mini saw to cut the portion I wanted to replace up and then cut off the rusted screws with a dremel. This is a super handy tool - great for small projects, and more useful than a large circular saw for most casual users, though I'm sure a pro would find many uses for it as well.

Parfait Utile
Cette scie se manipule facilement et sans encombrement de fils puisqu'elle est alimentée par une batterie (qui n'est pas fourni lors de l'achat). Par contre, si tu possèdes déjà une ou des batteries Dewalt cet achat est parfait (moins cher qu'avec l'achat d'une batterie). Coupe très bien le bois avec sa petite lame. De plus, vu que celle-ci est plus petite, elle est moins lourde que les grosses scies circulaires. Cet outil a facilité nos travaux pour le patio, dans la maison. Le seul regret que nous ayons, moi et mon conjoint, c'est de ne pas l'avoir acheté avant. De plus, cette scie sera parfaite pour les petits travaux futurs, nous voyons cela comme un très bon investissement. Un achat fort utile et sans aucun regret car très bon produit pour la qualité/prix.
