Customers say

Customers find the joiner offers good value for money and works well, with one customer noting it performs as well as higher-priced tools. Customers disagree on the accuracy of cuts and stability, with some reporting that once set it stays in place while others find it wobbly, and while some appreciate the easy adjustments, others find them difficult to set accurately.

Excellent biscuit joiner

Tyler H—January 29, 2026✓ Verified purchase

This biscuit joiner works amazing for the work I do. I tested with 100+ biscuits in solid alder using the factory blade and it worked great! The alignment is perfect and nice and tight. I really was amazed at the quality for the price. WEN tools have always been great for me Read more

WEN tools have gotten better over the years.

Midwest Hacker—January 25, 2026✓ Verified purchase

If this was a DeWalt or a Bosch I would give it a 4 star review. But at this price point, it works fine. Typical brush smell on first startup. Calmed down after a bit. Plenty of power. Seems fine for the little bit that I need this. Read more

Good tool for the money, amazon sucks.

N21K—August 5, 2025✓ Verified purchase

If you need something on time, don't buy from Amazon. Consistently sucking delivery. Prime crap. The tool is pretty good, actually, once you tighten up the fence and fine-tune the depth adjustment and change the blade, which you should do immediately. I purchased an 8 tooth freude blade with it, it will work very nicely and accuratly. It does rattle when it breaks, not sure why, but it seems to work fine. Also, a tool like this requires a lot of care. It's too bad they don't give you a case for it. Read more

Great value

Customer—January 21, 2026✓ Verified purchase

Works well and does exactly what it's supposed to do. For just a bit over $50 getting a hard case is a nice perk. I can't imagine spending $200 for the same tool just for it to be brand name and a battery powered. Read more

Awesome and very handy tool to have around the house or shop

Avid Amazon User1111—December 25, 2025✓ Verified purchase

I needed this for a special project, and not ever having used one before, I was extremely impressed with 1) how incredibly easy this tool was to use 2) how well it works and 3) how incredibly strong the joints it produces are. That said, I wish I had bought one of these years ago!!! Read more

Great tool for the price

Chuck—October 20, 2024✓ Verified purchase

Just received this the other day, and had my first opportunity to use it yesterday. Setup is very easy (except for the depth adjustment) and works very well overall. The only real flaw in its operation is the dust collector. This chute is very narrow, and clogged almost immediately. The collection bag provided barely had any sawdust, as it couldn't get through the chute. I would have to vacuum it out after every few cuts. The other negative of this tool - and the reason for 4 stars - is the depth adjustment. The lock-nut is an odd size - I think 7mm though I haven't found a wrench that fits yet, and it comes with so much thread lock on the tiny screw that it is really hard to turn (I had to adjust mine for the harbor freight biscuits I bought because their #0 were just slightly larger than the one that came with the cutter. Overall, I do recommend this tool for the price. I can't imagine the need to spend hundreds of dollars for something where the $50+ I paid does the job. I only wish I had owned one of these tools years ago! Read more
