Purchased this for my son who is an engineering student and had asked for a caliper for Christmas. Wanted to purchase a “lifetime” tool for him and after doing much research, settled upon a Mitutoyo. Global Test Supply had the best prices on Mitutoyo Calipers, and the company had excellent reviews online. I was impressed with the shipping speed as well — it arrived a couple of days after I ordered it. My son is very happy with the quality and feel of this tool. Would purchase from Global Test Supply again. Love that it is a USA company and that they carry authentic, high quality tools.

Thank you so much for choosing us for such a meaningful gift. We’re honored to be part of your son’s journey and truly appreciate your trust in us. It means a lot to hear he’s happy with it! We look forward to working with you again in the future.
The product I ordered took 3 months to ship and arrive. Don't sell me something that is out of stock if you don't plan on telling me it is out of stock.

We're glad to hear everything went well from start to finish! Thank you for sharing your feedback, Genia. If you need anything else, you know where to find us.
I purchased 4 high low thermometers and 3 didn't work at all and one didn't work correctly. I have tried to get them to give me replacements or my money back and I didn't get either. Just a big run around with minimal to no responses.

We're very sorry to hear this, Constantin. We've opened a ticket to look into this matter further, and will be in contact as soon as possible.
GTS sold me tools which I can’t use in USA because of it designed to be used for 220V and comes with power cords for Europe power outlets. But this information was not provided on tool description and I discovered it upon tool delivery. I requested return and refund. GTS said that it is my fault that I didn’t checked somewhere else that this tool is not compatible with US outlets, and charged me 25% restock fee for return, even I requested return because of misleading info on tool description. All this experience was similar with fraud.

I placed order 709972 for recovery machine and upon delivery I discovered that this machine designed for european power 230V and I can't use it in USA. This information was not listed in description on GTS website for this tool. I requested return for refund, but GTS said that it is my fault that I didn't make more research on this tool on internet and I should pay for my fault 25% restock fee. GTS didn't took they responsibility provide on tools correct information and did't accept their responsibility on this misleading info on their web that let me purchase this tool.

We sincerely apologize for the inconvenience this caused you, Phanet, and appreciate you bringing this matter to our attention. Due to the unexpected delays with the replacement shipment, we issued a full refund instead. We have also reviewed this situation internally and reinforced our procedures to prevent this from happening again.
I'm very confused by my purchase. I purchased an electronics vacuum and filter through their website for a reasonable price and received it within a few days. I thought that was it. Today I received a bill for $0.01 that apparently wasn't charged when I purchased the item through their website. How does that happen? How do you reserve one penny to be charged at a later date? Just charge me what it actually costs. One penny isn't worth your accounting department's time or mine. Very frustrated.

We’re sorry for the confusion on this order. Occasionally, minor tax rounding differences can occur on web orders, and this one-cent balance appeared on your statement before we were able to adjust and write it off internally. We’ve reached out by email with additional details. If you have any other questions, please don't hesitate to discuss with our accounting team.
