Review: BEST straight line tool! - Wow, wow, wow! I brought this at the point I was losing the will to live trying to obtain a perfect straight edge with frog tape, taping knife etc. I literally had had enough, so went on an impulse buying spree on desertcart to find ANYTHING that would work, no matter the cost... Came across this and the sound reviews, and was still sceptical, as everyone knows in order to achieve a straight line with a brush, you've gotta have a bloody good steady hand to do so, hence why it's so tricky, and most people just use tape. Fast forward to yesterday evening, I started "filling in" the edges before painting again, and seriously, this brush is amazing, like some sort of miracle! It has a triangular brush face, it is good for corners and getting a perfect straight line, even on uneven walls - I will upload some photos later, but anyone would think a professional did my walls! I will NEVER use frog tape again, this is my new go to! Nothing is "perfect" per'say, but this wins hands down against the perfect straight line follwowed by stupid bleeding and slight smudge marks you get with tape as you pull it off the wall. Definitely invest in this, it is just fantastic, I can't explain it enough!
Review: Paint like a pro - Does what it says on the tin and more. Faced with the task of cutting in some bold colours in multiple rooms I decided to buy this brush having read reviews about it and it is without doubt the best brush I have ever used. I have tried various gadgets over the years for cutting in but this really does work - all you need is a steady hand. The paint load to the tip gives a steady and consistent stream to give crisp and sharp edges. It has a tin opener at the end of the handle as a nice bonus. Should be your go to tool in your diy arsenal!

## Questions & Answers

**Q: How does this keep lines straight?  And whats your tips for  this brush?**
A: You still need a steady hand to get your lines straight. I wouldn't get another of these brushes; I didn't think it was that great. A wider bristle (1.5  inches) on an angled brush I find better than this one for doing neat lines alone ceilings etc. It's personal choice.

**Q: Brush fell apart after using it in two rooms is this normal?**
A: We would recommend contacting the customer service team to look into this for you.

**Q: i have a large window made up from 15 small windows, i am not looking forward to paining them, is this the tool i need ?**
A: Depends how big all the little windows are. I found it really useful with edges of walls skirting etc.  Useful brush without a doubt. Every home should have one

**Q: Would this help with ceiling trim as well?**
A: You may find it easier to apply paint to ceiling trim with this brush.

### ⭐⭐⭐⭐ Great brush for small wooden windows
*by E***Y on 10 August 2019*

I looked at the reviews and went for this brush, I have a whole house full of wooden windows that have not been looked after since they were put in 12 years ago. When we moved in this was the first job. the brush is great for cutting in and holds its paint well. The shape is perfect and is easy to use. As other reviews have stated the brush does get a bit claggie near the handle but a good wash will sort it out. If the had supplied a bristle comb that would have been worth 5 stars.
