Top 15 Best 123 blocks Picks For 2023

People always want the best product based on what they want, but most of the time, they’re just given products with overly-exaggerated features when in reality, it’s mediocre at best. But overall, the material, brand, and features most of the time decide how you can buy the best 123 blocks.

However, a better product oftentimes can cost too much money, most of which simply is because of the brand or the “features” which in reality aren’t that helpful. It’s important to have the perfect balance between the material, cost, and features themselves.

Expensive isn’t always better, since they might just have slightly better material or features which you won’t need. So to find out how you can buy and get the most out of it, you can check out our buying guide.

123 Blocks Attachment Hardware Kit

Popularity Score 9.5
Quality Score 9
Sentiment Score 9.6

Highlighted Features

  • Many inexpensive 123 Blocks contain numerous holes allowing them to be bolted together to increase their usefulness. Several problems arise when attempting to join several blocks together: 1) the holes in the sides and faces are not the same distance from the edge and when different faces are bolted together these are steps or offsets, and 2) using readily available bolts and nuts will leave hardware proud of the block’s surface interfering with the task at hand.
  • This 123 Block Attachment Hardware Kits addresses the above bolting limitations. This hardware allows joining blocks together with all hardware buried within the blocks. The hardware is also slightly smaller than the holes allowing edges and faces to be joined together with faces being flush with each other.
  • This hardware kits contains the following parts: two each 7/8 inch long by 5/16 inch diameter 8-32 threads dowels, two each 7/8 inch long by 5/16 inch diameter through hole dowels that fit 8-32 bolts, two each of the following length 8-32 Allen Head Cap Screws 1-1/2 inch, 2 inch and 2-1/2 inch, 9/64 inch hex key and a small flat screwdriver tip.
  • To use, insert a through hole dowel into a block hole and thread a screw through the hole. Next insert a threaded dowel into a hole in another block and screw and tighten the screw t into this nut to secure two blocks together. Each dowel has a straight screwdriver slot in line with the hole to assist in getting the dowels perfectly lined up to accept the bolts. The included screwdriver tip can be inserted in the slot to help in getting the dowels lined up to accept screws.
  • Using this hardware allows two blocks to be attached to each other in literally every possible configuration. Comes in telescoping plastic storage tube. Patent pending.

Bottom line, this product is finesse for use, features that meet consumer needs and give customer satisfaction and conformance to standards.

Thing to Consider Before When Buying Best 123 blocks

Here’s a detailed buying guide for 123 blocks to help you pick the perfect option —

Material

The first thing you should consider when getting products like 123 blocks is the material used for it and the quality. If you have a good product with a lot of features and it seems great, it’s nothing if it isn’t the same after a few months because the quality simply isn’t good.

Low-quality products often don’t work the same after just a few weeks or months, so it’s incredibly important to ensure the quality is good enough.

As a general rule of thumb, you should look for certifications on the quality and if it gets damaged easily. Popular brands often have good products, and you can also check the material specifications directly from the description.

Features

A lot of the time, people try to find the products that seem the most appealing with many features which are very rarely used. So you should ensure that when you’re buying something, you aren’t buying it simply because it has many features. You should look for the features you think you would often use, not niche features that are rarely used.

So more isn’t always better, just find which features you think you would use often enough to make it useful and convenient.

Price

Make sure that the price of the product isn’t too much, since a lot of the time, most of the price is based on the brand and the features, which in reality aren’t even that useful.

However, this doesn’t mean that you should always go for the cheapest option. Most of the time, if a product seems very cheap while having a lot of useful features, it won’t last a very long time and the performance can get worse very quickly.

Just make sure that you aren’t paying too much; you can find out if you’re paying too much by comparing other products of similar quality most of the time.

Reviews

A good way to tell if the product you’re buying is worth it or not is by checking the customer reviews. Most people check the 5-star reviews and think that the product is good, but you should instead check the negative reviews associated with it. Negative reviews can often tell about the nuisances with the product or what problems they’ve faced, which is quite helpful.

Try to check the 1-3 star ratings more, as they tend to point out the most common problems with the product. You should check a few 5-star reviews to see if the product is worth it or not, too.

Warranty

Finally, you should try to find products that have a warranty or guarantee of at least a few months. This can make sure that even if there are a few problems with the product, you can get it fixed or replaced without many issues.

It isn’t a must for the product, but it’s definitely convenient to have. It’s even better if you can have a money-back guarantee, too.

FAQs

To clear any further questions about 123 blockss, you can check out the most frequently asked questions we get —

Should I get a product even if it seems expensive?

If you’re trying to buy 123 blocks, but there’s a more expensive and premium version, you shouldn’t get it instantly because it’s “better”. Although premium products generally have better quality and tend to last longer, you should make sure that the price isn’t too much.

But if it’s a reasonable price and you can afford it, you should go for the premium version. They generally last much longer and it’s easier to fix the issues if something happens.

Is it better to look for cheaper alternatives before buying a product?

When you’re looking to buy a product such as 123 blocks, but you find similar products with cheaper price points, you shouldn’t instantly buy that one. If the original product is from a trusted brand and it’s reliable, then you shouldn’t always get the cheaper alternative as it can be low-quality.

But if you see that both of the brands are trusted and one is cheaper, you can go for the cheaper one. You shouldn’t waste too much time trying to find cheaper alternatives, but you should first look for a few options.

Are guarantee and warranty the same thing?

No, the guarantee is when they’re willing to fix or replace the product entirely for free, and the warranty is when they’re willing to fix the product for damages of specific parts or components.

CONCLUSION

Most of the time, there are just a lot of products and options to pick from, so choosing the right best 123 blocks can be quite difficult. We’ve covered the best ways to pick the product in this article, and we cover things like price, quality, features, and much more.

Generally, you should try to get a good enough warranty, if possible, with the product and, in the best case scenario, a money-back guarantee, and make sure the product isn’t overpriced by comparing the prices of competitors.

It shouldn’t be too low in quality, so the cheapest option isn’t always the best. You can check the 1-3 star rating reviews for any issues and the 5-star reviews if you want to check if it’s worth it or not.
