## Description

From the manufacturer

Review: Good value for money with decent buy options, but get rusted quickly. - Amazing product. Battery life is good. Good value for money. Has decent number of bits to work with. But a few of my tips got rusted already.
Review: Nice product but... - I'm writing this review after 2 and a half months since my purchase. I use it for my homely purpose and not for anything heavy. The screwdriver is not weak or not very much powerful, and does a decent job. I'm not going to do an in-depth review of this item since many people have already done it. I'm writing this for those who have faced an issue with this screwdriver wherein it STOPPED WORKING ABRUPTLY. I use it occasionally and the last day when I used it; it stopped working all of a sudden. At first, I thought of claiming a warranty but from previous reviews, I realized that it is not an easy thing to do as they drag the warranty process for months. That is when I decided to open it myself even though it could void the warranty I decided to take the risk. When I opened it, I saw the wire point that connected to the push and start switch was broken (see highlighted portion in the pic). This is due to the rigidness of the wire connection here. So, I fixed it with an insulated flexible wire from an old transformer, and started working again!!! Basically, this could happen to any of you who purchase/d it; I would blame BLACK+DECKER for not using a proper flexible wire connection method suitable for the push and start switch. Hope that it will be helpful to some people.

### ⭐⭐⭐⭐⭐ Black and decker bd40k27
*by M***K on 24 July 2025*

The electric screwdriver driver is good. But the magnet is not that much great to hold bits and screws. It comes with mini size screw driver with limited bits. Mostly it's not usefull. It's takes more than 2 hrs for full charge. The draw back is we can't check the battery level. The battery level indicated only while charging.
