Sequre SQ-ES126 Electric screwdriver review and comparison to other Precision drivers

16/10/2021

4 Comments

 
The Sequre SQ-ES126 is a top of the range compact electronic precision screwdriver that has been made for very precise work such as small scale RC Cars and quadcopters. These small screwdrivers can significantly speed up your build and repairs, especially when you have long screws! This in not a cheap tool though so in this review I’ll give you all the details to help you understand if it is the right tool for you.
Picture
Before we get stuck in to this review let just define the difference between cordless/impact drivers (like you might use for building/home rennovation) and the precise compact drivers like used here. 
Picture
Cordless impact drivers are an evolution of the cordless drill. They are big, heavy and generate a lot of torque, So much so that they easily strip the small screws used on RC Cars and quadcopters. Ask me how I know!
Picture
Precision Electric screwdrivers like the SQ-ES126 reviewed here and the wowstick range are used for fine work - as big as RC cars and as small as consumer electronics such as laptops and mobile phones. The best ones have adjustable torque setting to ensure even the finest screws are not at risk of stripping. They are light and about the same size as a regular screwdriver.
What's included in the pack?
When you buy the product you'll receive the following items in the pack:
  • 1 x SQ-ES126 Smart Screwdriver 
  • 24 x M4 Screwdriver Bits and magnetic carry case. 
  • 1 x Manual Handle
  • 1 x Instruction Manual
Picture
The screwdriver bits contain all the main ones you need for fine work - a good range of Posidrive (Philips), Hex drives in 1.5mm and 2.0mm. I'm a little disappointed that there is no 2.5mm hex drive but my guess is that the lack of torque that these precision drivers can generate is not enough for a 2.5mm head screw. The good news is that M4 driver bits are very common.
The manual handle is a nice touch but to be honest the bits are so easy to change I don't know why you just wouldn't use the main driver.
Comparison to other electric drivers.
Picture
​SEQURE SQ-ES126: 0.28NM torque, $106
Picture
​Wowstick 1F+ 64 In 1: 0.15 Nm 200rpm $31
Picture
​XIAOMI Mijia: 0.2NM 200rpm $31
Picture
​Wowstick 1P+ 19 In 1: 0.12 NM 150rpm $16
Picture
​Wowstick 1+: 0.15NM, 200 RPM $86
As you can see it completely outclasses the other drivers, particularly in torque which is the most important measure. In use it means that this will remove practically any screw on a 1/10 and smaller RC car or any quadcopter that is not held in with Loctite – typically m3 or smaller. This screwdriver offers probably the minimum amount of torque I’d want – I’d be wary of going less although the Xiaomi Mijia makes for a good option to consider at the price point.
How to operate the SQ-ES126
This electronic screwdriver has quite a nifty way of operating thanks to the  STM32 chip in it - the same brain used in quadcopter flight controllers. If you hold the lower button and twist in the direction you want to tighten or loosen then the motor will run in that direction. This feature is more clever that it sound because it means you can loosen a tight screw bind with the assist of your hand before the screwdriver takes over. The other button does exactly the same think but with a light on. I question why this couldn't be just one button but it's probably because you need two buttons to scroll though and change menu settings.
Picture
The screen between the two buttons is a crisp single colour OLED and displays the battery level and the torque setting. For RC cars I keep the torque setting a maximum (which is 1) but you can also reduce torque for very small items like watches, phones etc by choosing 2, 3 or 4.
The USB type-c port on the rear of the driver helps allows you to charge of course with a standard 5v phone charger (not included) but also allows you to update the firmware, not that I can see that being particularly crucial. Speaking of the battery I've been using mine fairly consistently for the last 3 weeks and I'm only down to 1 bar now.
Picture
What is it actually like in use?
I've gotta say this driver is a truly decadent treat when you have a lot of screws to work with or a lazy. I'm a bit of both so this suits me well! For quadcopters I think this is a perfect tool because there is no ongoing bind on screws since they are typically mated to a threaded nut or fitting. Because RC cars have screws that go into plastic though there is more ongoing bind as a rough rule I'd say the torque on only really for cars that are 1/10 scale and smaller. the speed of rotation on this unit is very good and will undo even a long screw quickly, 

The weight of the tool is extremely satisfying and it makes the level of quality seem all the more real. The finish is of high quality and the alloy outer looks like it could take a drop off the workbench or two.

The angle sensing control method is surprisingly intuitive and as mentioned encourages you to use the torque from your wrist to remove the initial bind before the driver takes over.
Picture
The driver bits fit in the driver nicely with a satisfying magnetic hold meaning no quick release sheaths are needed. This also provide just enough magnet strength to hold the screw to the tip which is handy with these small and fiddly screws.
Conclusions, Recommendations
At around $100 at full price this is an eye wateringly expensive tool of convenience but compared to the competition, it is in a class of it's own for torque which is the most important element of this driver. The closest comparison is the Xiaomi Wowstick at only $ but with % less torque and % less rpm.

If you can get past the price it is a lovely tool to use - it feels great in the hand and makes building much more pleasant. Battery life is excellent and the included bits and holder are simple and practical. If you are in the market for a such a tool, this is the one to have; it has already become the tools that sits closest to my work area.

I bought the xaiomi a while back and love it. Makes working on your cars a treat and wards against my already growing RSI afflictions.

That said I only have one 1/10 scale with everything else being smaller. Sometimes you do have to loosen the odd screw before using the xaiomi but it’s still a massive quality of life tool for very little money.

I think I paid less than £20 for mine on a flash deal. Definitely recommend!

I’d love to buy this one too, but but out of my budget. Looks great though.

Can you perhaps recommend a decent Dremel type tool for small scale polishing/cutting etc.

I bought this after reading your review and it seems like a really nice little tool that is easy and intuitive to use, although I can't speak for its long-term quality. I have done a fair few upgrades to 1/10 Traxxas RC cars in the last few weeks, due to self-isolating and free time over Christmas and it has definitely helped take some of the donkey work out of the many screws to be removed and refitted. It struggled for torque a few times, but I prefer to do initial loosening or final tightening manually anyway.

As is often the case with Chinese products, the instructions are not great. When you enter the menu to adjust torque, it is not clear what happens if you set the driver on A or P instead of selecting the torque values 1-4. Whatever mode or torque I have set, mine seems to do much the same and still senses rotational direction when the A/B button is pressed. Still a mystery!

The selection of bit tips is good. In your review I see yours omitted a 2.5 hex, which, as we know is a very useful bit for 1/10 RC. Mine came with 1.5, 2.0 and 2.5 hex. There is only room for 2 hex bits in the magnetic slots and the third one was resting next to the manual driver, so I wonder if it is now being included due to customer complaints or an acknowledgement that 2.5 is an important size to have. Might be worth you contacting customer service to see if they can send you one?

My only real irritation so far is with the bit case. It seems a generally good design and organises the bits well....but! It is like holding a bar of soap with its slick surface (and my dry winter skin) and it has now slipped out of my grip 3 times, scattering bits all over the floor. It is like a time-consuming puzzle trying to put them all back in the correct place. The case needs to be textured for grip and have a clip closure rather than magnets, so it remains closed even if dropped. I keep an elastic band around it at all times now, having learned my lesson!

Thanks for the review,

Cliff

Still can't bring myself to spend this kind of money on an electric screwdriver. But maybe some RC fan would like to spoil him/herself for christmas?
