### ⭐⭐⭐⭐ Quality, function and value are all included.
*by H***H on May 19, 2018*

I would give this product a 4-1/2 stars if this was possible in the rating system. I like it very much, but not enough to say that I love it. I was looking for a quality tape measure that provided both inch & metric measurements and was not too large. This product also provides a diameter conversion measurement (when you measure the circumference/perimeter of a round object), which is a definitely a valuable capability. The quality, materials & finish are quite good and are somewhat better than I expected at this price point; this product should last a long time under moderate use. The 1/2" wide (12 foot/3.65 meter) steel tape is very strong/robust. The measurement/marking lines and numbers are very clear/easy to distinguish (high contrast). The tape measure size/storage footprint is just right for my needs; not nearly as bulky as some alternatives but large enough to get a good handle on. The spring loaded, tape retraction action is smooth & fast. The only reason for not rating this a five star product; it has a rectangular ring end on the tape versus a 90 degree bent metal end catch. This requires two hands for the type of measurements that I make most of the time. However, this is a fundamental trade off; it will work better under some measuring conditions. They should probably provide an optional 90 degree bent metal end catch version or clip on. Also, it does not have a lock on the tape; you have to effectively "lock it" with your fingers. This is not a large disadvantage, but I would pay more for this function because it can free up a hand under certain measurement scenarios. This product is highly recommended. It should be noted that I was motivated to post a review of this product because I would receive a free "silicone snap ruler" from the vendor. However, I stand by my review as an authentic reflection of my assessment of the product.
