    A fantastic glue gun

    I had tried a number of other glue guns with Polyamide glue sticks with no success- The TEC 820 performed all day no problems at all.

    The temperature control was very helpful as I was able to lower the temperature slightly which enabled better glue control

    I use to use the old 901 gun, but this replacement is far superior, quality is excellent

    Works like charm. Heats up quickly, trigger adjustment allow for really precise application whether you need quick delivery of large glue quantity or small precise amount.
    Option for different nozzles extends usability making it excellent professional tool.
    I had chance to use it so far for making custom cardboard boxes and some woodworking assembly work. Excelent results when used to hold small decorative parts in place while wood adhesive cures. No more pinholes to fill after small nails been used to hold in place.

    Overall great tool.

    This is as much like the normal hobbyist 16W or 24W glue-gun as a Rolls Royce is like a pram! The main difference is the rapid but regulated flow from this large but light 240W device. It’s continuous and as fast as you want. Then you can put the gun straight down (I kept the stand on) and it doesn’t dribble at all. The large trigger makes the thing easy to use too. I’m delighted with it! The one mystery is the three small parts clipped underneath. I still can’t work out what they are for! Martin (of Inclusive Technology).

    Hi only used this gun twice so far,but very impressed with it , glued a wood joint with the all purpose glue that came with the gun, do not think it’s meant for wood but I tried it,and I can not break the joint the wood split first so very impressed, now bought some glue for wood can’t wait to try this .

    Very nice, i bought this one as an upgrade from the TEC805 for the ability for both hot and cold melt. The unit is very efficient warming in no time at all and has a good through rate (Kg per hour). I am impressed with this unit.

    A delight to use. Well balanced and the stand is very stable. The cover to the nozzle is awkward to remove to expose the thread and I will not put it back. A less rigid cable, e.g. genuine rubber, would help stability.

    Order the 820 for a couple of reasons 1. It has variable temperature control and 2. It has a nozzle which is not too big or small
    The order placed and gun received very quickly. have used it already on a a number of things already from sealing the flaps on cartons the bond here is strong and delivery is quick. I equally used it to make cards using the fine detail nozzle so on the whole does a wide variety of jobs and does it well. Highly recommended

    Surprisingly light easy to handle glue gun. Useful to hold the stand with free hand while guiding the glue. Heats up quickly. Slight glue drip between between uses but not a problem.

    A good quality product and made in Britain. I did not like the very stiff mains lead. Replaced it with a much more flexible rubber one that made it a delight to use.

    Great product, have wondered about getting one for some time but thought they were too expensive for my needs. Very happy that I did buy one, much better than I thought don’t know how I managed before. Excellent service won’t hesitate to use again.

    Excellent tool! I bought it for general use with my first need to re-apply sisal rope to a cat scratching activity centre. This tool was perfect – easy and comfortable to use, plenty of glue at all times and very controllable. My previous experience with hot glue was with a small Bosch craft type gun which gave dreadful results – glue that hardened almost immediately and had little adhesion. In contrast my TecBond 820 delivers a good quantity of glue that stayed liquid for long enough to position my work and soak into the rope before forming a strong bond, even in quite cool conditions. (Used type 5 glue). Very impressed and glad I bought this tool. Great service from Gluie Guns direct who took the trouble to check with my my needs to ensure I had ordered the correct products. Great! Shall be a returning customer.

    A good product works fine and well made in UK. I purchased the 820 with a selection of 1 kilo packs of glue sticks and accessories. Polypropylene is one of the most common plastics but the 263 glue stick for bonding polypropylene is only available in 5 kilo packs that I believe is a far to great for many users needs. Hence the score. Otherwise a great product and service.

    Purchased this gun to attach cloth / felt onto pool table slates. Wish i had come across it years ago as we have been through a large selection of guns and none come anywhere near the performance of these. As soon as we tried it out we ordered 2x more. We get through alot of glue and these guns deliver a constant stream of it without having to wait for more to melt in the chamber, our old glue guns couldn’t deliver enough glue so we were forever waiting for the guns to catch up. Slightly more expensive than the guns we have had in the past but well worth the extra and will pay for themselves in the time that we save. Would recommend to anyone who uses glue guns on a regular basis.

    I used the Tecbond 806 hot glue gun with Tecbond 261 glue sticks. It needed a couple of minutes to warm up, but performed perfectly.

    Bonding different plastics together was my problem for artwork. Foamex board plus closed cell foam plus polystyrene requires some control over how hot materials get and that is where a variable thermostat glue gun was needed. Glue sticks cam melt at slightly lower temperatures than specified so that materials like foam do not melt down instantly. This gun is worth the extra expense over basic models, heats up quickly, handles well and will last, clearly well made …. a good investment tool for creatives.

    Helen Sinclair (verified owner)

    Brilliant product. Everything I need (a sculptor mostly glueing wood). A glue gun that heats quickly and pushes through the glue at great speed continuously. The nozzle allows relatively precise placement of glue and the gun creates a really strong bond (with multi-purpose glue sticks). I often use it for hours at a time and it copes with it easily.
